Noun
DNA sequence (plural DNA sequences)
(genetics) The string of base pairs (adenine, thymine, cytosine, and guanine) which, when arranged in triplets to form codons, create a DNA string which encodes polypeptides.
A cladistic analysis of DNA sequence data of the S7 ribosomal protein intron 1 supports the view that it is distinct enough to constitute a monotypic subfamily. Source: Internet
A consensus definition of the concept of epigenetic trait as "stably heritable phenotype resulting from changes in a chromosome without alterations in the DNA sequence" was formulated at a Cold Spring Harbor meeting in 2008. Source: Internet
An insulator in a DNA sequence is comparable to a linguistic word divider such as a comma (,) in a sentence, because the insulator indicates where an enhanced or repressed sequence ends. Source: Internet
A mutation is a tiny alteration that occurs to genetic materials like our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors. Source: Internet
As noted above, there are many different kinds of DNA sequence variation, ranging from complete extra or missing chromosomes down to single nucleotide changes. Source: Internet
Because transcription factors can bind a set of related sequences and these sequences tend to be short, potential transcription factor binding sites can occur by chance if the DNA sequence is long enough. Source: Internet
