A tract of repetitive DNA in which a motif of a few base pairs is tandemly repeated numerous times (e.g. 5 to 50 times) is referred to as microsatellite DNA. Thus direct repeat tandem sequences are a form of microsattelite DNA. The process of DNA mismatch repair plays a prominent role in the formation of direct trinucleotide repeat expansions. [2]
The expression "macaroni and cheese" is an irreversible binomial.The order of the two keywords of this familiar expression cannot be reversed idiomatically.. In linguistics and stylistics, an irreversible binomial, [1] frozen binomial, binomial freeze, binomial expression, binomial pair, or nonreversible word pair [2] is a pair of words used together in fixed order as an idiomatic expression ...
3' untranslated region (3'-UTR). Also three-prime untranslated region, 3' non-translated region (3'-NTR), and trailer sequence.. 3'-end. Also three-prime end.. One of two ends of a single linear strand of DNA or RNA, specifically the end at which the chain of nucleotides terminates at the third carbon atom in the furanose ring of deoxyribose or ribose (i.e. the terminus at which the 3' carbon ...
The intervening sequence of nucleotides between the initial sequence and the reverse complement can be any length including zero. For example, 5'---TTACGnnnnnn CGTAA---3' is an inverted repeat sequence. When the intervening length is zero, the composite sequence is a palindromic sequence. [2]
The meaning of palindrome in the context of genetics is slightly different, from the definition used for words and sentences. Since the DNA is formed by two paired strands of nucleotides, and the nucleotides always pair in the same way (Adenine (A) with Thymine (T), Cytosine (C) with Guanine (G)), a (single-stranded) sequence of DNA is said to ...
In genetic sequence alignments, gaps are represented as dashes(-) on a protein/DNA sequence alignment. [1] Unix diff function - computes the minimal difference between two files similarly to plagiarism detection. Spell checking - Gap penalties can help find correctly spelled words with the shortest edit distance to a misspelled word. Gaps can ...

Complementarity between two antiparallel strands of DNA. The top strand goes from the left to the right and the lower strand goes from the right to the left lining them up. Left: the nucleotide base pairs that can form in double-stranded DNA. Between A and T there are two hydrogen bonds, while there are three between C and G.
