Abstract
DNA-encoded library (DEL) technologies are transforming the drug discovery process, enabling the identification of ligands at unprecedented speed and scale. DEL makes use of libraries that are orders of magnitude larger than traditional high-throughput screens. While a DNA tag alludes to a genotype-phenotype connection that is exploitable for molecular evolution, most of the work in the field is performed with libraries where the tag serves as an amplifiable barcode but does not allow "translation" into the synthetic product it is linked to. In this Review, we cover technologies that enable the "translation" of the genetic tag into synthetic molecules, both biochemically and chemically, and explore how it can be used to harness Darwinian evolutionary pressure.

Nucleic Acids Res 2020; 48:11982-11993.

Abstract
A set of modified 2′-deoxyribonucleoside triphosphates (dNTPs) bearing a linear or branched alkane, indole or phenyl group linked through ethynyl or alkyl spacer were synthesized and used as substrates for polymerase synthesis of hypermodified DNA by primer extension (PEX). Using the alkyl-linked dNTPs, the polymerase synthesized up to 22-mer fully modified oligonucleotide (ON), whereas using the ethynyl-linked dNTPs, the enzyme was able to synthesize even long sequences of >100 modified nucleotides in a row. In PCR, the combinations of all four modified dNTPs showed only linear amplification. Asymmetric PCR or PEX with separation or digestion of the template strand can be used for synthesis of hypermodified single-stranded ONs, which are monodispersed polymers displaying four different substituents on DNA backbone in sequence-specific manner. The fully modified ONs hybridized with complementary strands and modified DNA duplexes were found to exist in B-type conformation (B- or C-DNA) according to CD spectral analysis. The modified DNA can be replicated with high fidelity to natural DNA through PCR and sequenced. Therefore, this approach has a promising potential in generation and selection of hypermodified aptamers and other functional polymers.

Abstract
Expanding the chemical diversity of aptamers remains an important thrust in the field in order to increase their functional potential. Previously, our group developed LOOPER, which enables the incorporation of up to 16 unique modifications throughout a ssDNA sequence, and applied it to the in vitro evolution of thrombin binders. As LOOPER-derived highly modified nucleic acids polymers are governed by two interrelated evolutionary variables, namely, functional modifications and sequence, the evolution of this polymer contrasts with that of canonical DNA. Herein we provide in-depth analysis of the evolution, including structure-activity relationships, mapping of evolutionary pressures on the library, and analysis of plausible evolutionary pathways that resulted in the first LOOPER-derived aptamer, TBL1. A detailed picture of how TBL1 interacts with thrombin and how it may mimic known peptide binders of thrombin is also proposed. Structural modeling and folding studies afford insights into how the aptamer displays critical modifications and also how modifications enhance the structural stability of the aptamer. A discussion of benefits and potential limitations of LOOPER during in vitro evolution is provided, which will serve to guide future evolutions of this highly modified class of aptamers.

Abstract
Ligase-catalyzed oligonucleotide polymerisations (LOOPER) can readily generate libraries of diversely-modified nucleic acid polymers, which can be subjected to iterative rounds of in vitro selection to evolve functional activity. While there exist several different DNA ligases, T4 DNA ligase has most often been used for the process. Recently, T3 DNA ligase was shown to be effective in LOOPER; however, little is known about the fidelity and efficiency of this enzyme in LOOPER. In this paper we evaluate the efficiency of T3 DNA ligase and T4 DNA ligase for various codon lengths and compositions within the context of polymerisation fidelity and yield. We find that T3 DNA ligase exhibits high efficiency and fidelity with short codon lengths, but struggles with longer and more complex codon libraries, while T4 DNA ligase exhibits the opposite trend. Interestingly, T3 DNA ligase is unable to accommodate modifications at the 8-position of adenosine when integrated into short codons, which will create challenges in expanding the available codon set for the process. The limitations and strengths of the two ligases are further discussed within the context of LOOPER.

Abstract
Ligase-catalyzed oligonucleotide polymerization (LOOPER) that enables the sequence-defined generation of DNA with up to 16 different modifications has recently been developed. This approach was used to develop new classes of diversely modified DNA aptamers for molecular recognition through in vitro evolution. The modifications in LOOPER are appended by use of a long hexane-1,6-diamine linker, which could negatively impact binding thermodynamics. Here we explore the incorporation of modifications with the aid of shorter linkers and the use of commercially available phosphoramidites and assess their efficiency and fidelity of incorporation. We observed that shorter linkers are less tolerated during LOOPER, with very short linkers providing high levels of error and sequence bias. An ethane-1,2-diamine linker was found to be optimal in terms of yield, efficiency, and bias; however, codon adjustment was necessary. This shorter-linker anticodon set for LOOPER should prove valuable in exploring the impact of diverse chemical modifications on the molecular function of DNA.

Abstract
The evolution of sequence-defined synthetic polymers made of building blocks beyond those compatible with polymerase enzymes or the ribosome has the potential to generate new classes of receptors, catalysts, and materials. Here we describe a ligase-mediated DNA-templated polymerization system and in vitro selection to evolve highly functionalized nucleic acid polymers (HFNAPs) made from 32 building blocks containing eight chemically diverse side-chains on a DNA backbone. Through iterated cycles of polymer translation, selection, and reverse translation, we discovered HFNAPs that bind PCSK9 and IL-6, two protein targets implicated in human diseases. Mutation and reselection of an active PCSK9-binding polymer yielded evolved polymers with high affinity (KD = 3 nM). This evolved polymer potently inhibited binding between PCSK9 and the LDL receptor. Structure-activity relationship studies revealed that specific side-chains at defined positions in the polymers are required for binding to their respective targets. Our findings expand the chemical space of evolvable polymers to include densely functionalized nucleic acids with diverse, researcher-defined chemical repertoires.

Abstract
Recent progresses in organic chemistry and molecular biology have allowed the emergence of numerous new applications of nucleic acids that markedly deviate from their natural functions. Particularly, DNA and RNA molecules-coined aptamers-can be brought to bind to specific targets with high affinity and selectivity. While aptamers are mainly applied as biosensors, diagnostic agents, tools in proteomics and biotechnology, and as targeted therapeutics, these chemical antibodies slowly begin to be used in other fields. Herein, we review recent progress on the use of aptamers in the construction of smart DNA origami objects and MRI and PET imaging agents. We also describe advances in the use of aptamers in the field of neurosciences (with a particular emphasis on the treatment of neurodegenerative diseases) and as drug delivery systems. Lastly, the use of chemical modifications, modified nucleoside triphosphate particularly, to enhance the binding and stability of aptamers is highlighted.

Abstract
We describe the application of T4 DNA ligase-catalyzed DNA templated oligonucleotide polymerization toward the evolution of a diversely functionalized nucleic acid aptamer for human α-thrombin. Using a 256-membered ANNNN comonomer library comprising 16 sublibraries modified with different functional groups, a highly functionalized aptamer for thrombin was raised with a dissociation constant of 1.6 nM. The aptamer was found to be selective for thrombin and required the modifications for binding affinity. This study demonstrates the most differentially functionalized nucleic acid aptamer discovered by in vitro selection and should enable the future exploration of functional group dependence during the evolution of nucleic acid polymer activity.

Abstract
A T4 DNA ligase-catalysed oligonucleotide polymerisation process has been recently developed to enable the incorporation of multiple functional groups throughout a nucleic acid polymer. T4 DNA ligase requires ATP as a cofactor to catalyse phosphodiester bond formation during the polymerisation process. Herein, we describe the structure-activity relationship of ATP within the context of T4 DNA ligase-catalyzed oligonucleotide polymerisation. Using high-throughput sequencing, we study not only the influence of ATP modification on polymerisation efficiency, but also on the fidelity and sequence bias of the polymerisation process.

The robustness of the method was highlighted in the copolymerization of a 256-membered ANNNN library comprising 16 sub-libraries modified with different functional groups. This enabled the generation of diversely functionalized synthetic nucleic acid polymer libraries with 93.8 % fidelity. This process should find ready application in DNA nanotechnology, DNA computing, and in vitro evolution of functional nucleic acid polymers.

Abstract
Recent advances in nucleic acid-templated copolymerization have expanded the scope of sequence-controlled synthetic copolymers beyond the molecular architectures witnessed in nature. This has enabled the power of molecular evolution to be applied to synthetic copolymer libraries to evolve molecular function ranging from molecular recognition to catalysis. This Review seeks to summarize different approaches available to generate sequence-defined monodispersed synthetic copolymer libraries using nucleic acid-templated polymerization. Key concepts and principles governing nucleic acid-templated polymerization, as well as the fidelity of various copolymerization technologies, will be described. The Review will focus on methods that enable the combinatorial generation of copolymer libraries and their molecular evolution for desired function.
