| recognition sequence | A nucleotide sequence --typically composed of 4, 6, or 8nucleotides -- that is recognised by a restriction endonuclease. Type II enzymes cut (and theircorresponding modification enzymes methylate) within or very near the recognition sequence. (09 Oct 1997) |
|---|---|
| regulatory sequence | <molecular biology> DNA sequence to which regulatory molecules such as promotors or enhancers bind, thereby altering the expression of the adjacent gene. (18 Nov 1997) |
| centromeric sequence | <molecular biology> Special sequences of DNA nucleotides found on chromosomes which provide a site for the attachment of spindle fibres during nuclear division (mitosis or meiosis). (09 Oct 1997) |
| chi sequence | <molecular biology> A specific sequence of nucleotides on a site on the genome of the bacteria Escherichia coli which strongly encourages recombination and crossing over to occur at that site. (05 Jan 1998) |
| PEST sequence | Amino acid motif that is thought to target cytoplasmic proteins for rapid proteolytic degradation. (18 Nov 1997) |
| molecular sequence data | Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as genbank, european molecular biology laboratory (embl), national biomedical research foundation (nbrf), or other sequence repositories. (12 Dec 1998) |
| coding sequence | The portion of DNA that codes for transcription of messenger RNA. See: exon. (05 Mar 2000) |
| monotonic sequence | A sequence in which each value in a set is greater than the preceding value. (05 Mar 2000) |
| complementary sequence | <molecular biology> Nucleicacid base sequences that can form a double-stranded structure bymatching base pairs, the complementary sequence to G-T-A-C is C-A-T-G. (09 Oct 1997) |
| consensus sequence | Of a series of related DNA, RNA or protein sequences, the sequence that reflects the most common choice of base or amino acid at each position. Areas of particularly good agreement often represent conserved functional domains. The generation of consensus sequences has been subjected to intensive mathematical analysis. (18 Nov 1997) |
| conserved sequence | <molecular biology> A base sequence in a DNA molecule (or an amino acid sequence in a protein) that has remained essentially unchanged throughout evolution. (10 Nov 1998) |
| sequence | The noun: the order in which subunits appear in a chain, such as amino acids in a polypeptide or nucleotide bases in a DNA or RNA molecule. The verb: To find out in what order the subunits appear in the chain. (09 Oct 1997) |
| sequence alignment | The arrangement of two or more amino acid or base sequences from an organism or organisms in such a way as to align areas of the sequences sharing common properties. The degree of relatedness or homology between the sequences is predicted computationally or statistically based on weights assigned to the elements aligned between the sequences. This in turn can serve as a potential indicator of the genetic relatedness between the organisms. (12 Dec 1998) |
| sequence, complementary | Nucleic acid sequence of bases that can form a double- stranded structure by matching base pairs. For example, the complementary sequence to c-a-t-g (where each letter stands for one of the bases in DNA) is g-t-a-c. (12 Dec 1998) |
| sequence, conserved | A base sequence in a DNA molecule (or an amino acid sequence in a protein) that has remained essentially unchanged throughout evolution. (12 Dec 1998) |
