Figure 3. DNA has (a) a double helix structure and (b) phosphodiester bonds. The (c) major and minor grooves are binding sites for DNA binding proteins during processes such as transcription (the copying of RNA from DNA) and replication....
We discuss retroviral, adenoviral, and herpes simplex type I (HSV)-based vectors. Retroviruses (12) are RNA viruses whose life cycle involves genomic integration, permitting long-term and inheritable expression of a gene shuttled by this virus. The simplicity of retroviral genomes has allowed the...
Fig. 1. Principle and technical parameters of TAC-seq.aSchematic diagram of the assay to detect specific mRNA or cell-free DNA. Target-specific DNA oligonucleotide detector probes hybridize under stringent conditions to the studied cDNA or cfDNA. Both detector oligonucleotides consist of a specific ...
In this article, we will specifically discuss the interplay of histone acetylation and methylation of H3 at lysines 4, 9, 27, and 36 and DNA cytosine methylation. Some of the data and models we discuss are summarized in a diagram in Figure 2. Sign in to download full-size image Figure ...
To model protein-nucleic acid interactions, it is important to identify the DNA or RNA-binding residues in proteins. Protein sequence features, including the biochemical property of amino acids and evolutionary information in terms of position-specific scoring matrix (PSSM), have been used for DNA ...
RNA-guided target DNA recognition unleashes the nuclease activity of SPARDA leading to indiscriminate collateral cleavage of DNA and RNA. Activation of SPARDA by plasmids or phages results in degradation of cellular DNA and cell death or dormancy, conferring target-specific population protection and ...

The enzyme reverse transcriptase synthesizes a DNA chain on an RNA template, and DNA polymerase converts the single-stranded DNA molecules into double-stranded DNA molecules that can further be used as templates (Figure 9.2, top). Then a PCR reaction is run to amplify a fragment of DNA to ...
