G-quadruplex structures can be computationally predicted from DNA or RNA sequence motifs, [11] [12] but their actual structures can be quite varied within and between the motifs, which can number over 100,000 per genome. Their activities in basic genetic processes are an active area of research in telomere, gene regulation, and functional ...
In molecular biology, linker DNA is double-stranded DNA (38-53 base pairs long) in between two nucleosome cores that, in association with histone H1, holds the cores together. Linker DNA is seen as the string in the "beads and string model", which is made by using an ionic solution on the chromatin .
NGS adapters are short ~80 BP fragments that bind to DNA to aid in amplification during library preparation and are also useful to bind DNA to the flow cell during sequencing. [5] These adapters are made up of three parts that flank the DNA sequence of interest. There is the flow cell binding sequence, the primer binding site, and also tagged ...
DNA parts and linker design. The DNA parts are designed and cloned into storage plasmids, with the part flanked by an integrated prefix (iP) and an integrated suffix (iS) sequence. The iP and iS sequences contain inward facing BsaI restriction sites, which contain overhangs complementary to the BASIC linkers. [48]
The purpose of an MCS in a plasmid is to allow a piece of DNA to be inserted into that region. [2] An MCS is found in a variety of vectors, including cloning vectors to increase the number of copies of target DNA, and in expression vectors to create a protein product. [3] In expression vectors, the MCS is located downstream of the promoter. [2]
A sequence profiling tool in bioinformatics is a type of software that presents information related to a genetic sequence, gene name, or keyword input. Such tools generally take a query such as a DNA , RNA , or protein sequence or ‘keyword’ and search one or more databases for information related to that sequence.
Ligation-mediated PCR uses small DNA oligonucleotide 'linkers' (or adaptors) that are first ligated to fragments of the target DNA. PCR primers that anneal to the linker sequences are then used to amplify the target fragments. This method is deployed for DNA sequencing, genome walking, and DNA footprinting. [12]
The second domain (A2) is adjacent to the A1 domain by a conserved linker sequence is a sequence of 21 amino acids vital in the specific DNA to CCAAT box binding. The A1 and A2 domains are conserved towards the C-terminus of mammals, but occupy a more central region in plant NF-YA subunits.
