| DNA typing | <molecular biology> See restriction fragment length polymorphism. (18 Nov 1997) |
|---|---|
| DNA unwinding protein | <molecular biology> A protein that will attach to single-stranded DNA after it has been unwound for replication or recombination, and help it stay unwound. (09 Oct 1997) |
| DNA, viral | Deoxyribonucleic acid that makes up the genetic material of viruses. (12 Dec 1998) |
| DNA virus | <molecular biology, virology> A virus in which the nucleic acid is double or single stranded DNA (rather than RNA). Major groups of double stranded DNA viruses are papovaviruses, adenoviruses, herpes viruses, large bacteriophages and poxviruses: of single stranded, parvoviruses and coliphages _X174 and M13. (18 Nov 1997) |
| DNA viruses | Viruses whose nucleic acid is DNA. (12 Dec 1998) |
| DNA writhing | <molecular biology> Coiling of a double-stranded DNA molecule in such a way that it crosses its own (longitudinal) axis. (09 Oct 1997) |
| double-stranded complimentary DNA | <molecular biology> A duplex DNA molecule copied from a copy DNA template. (09 Oct 1997) |
| dyad symmetry of DNA | <molecular biology> Two areas of a DNA molecule whose base pair sequences are repeats of each other, inverted relative to each other, or are palindromes. (09 Oct 1997) |
| O(2)-methylthymine-DNA glycosidase | <enzyme> Repairs o(2)-methylthymidine residues in DNA Registry number: EC 3.2.2.- Synonym: mth-DNA glycosidase (26 Jun 1999) |
| O(4)-methylthymine-DNA methyltransferase | <enzyme> Repairs o(4)-methylthymidine residues in DNA Registry number: EC 2.1.1.- Synonym: mth-DNA methyltransferase (26 Jun 1999) |
| o(6)-methylguanine-DNA methyltransferase | <enzyme> An enzyme that transfers methyl groups from o(6)-methylguanine, and other methylated moities of DNA, to a cysteine residue in itself, thus repairing alkylated DNA in a single-step reaction. Chemical name: DNA-6-O-methylguanine:protein-L-cysteine S-methyltransferase Registry number: EC 2.1.1.63 (12 Dec 1998) |
| technology, recombinant DNA | A series of procedures used to join together (recombine) DNA segments. A recombinant DNA molecule is constructed (recombined) from segments from 2 or more different DNA molecules. Under certain conditions, a recombinant DNA molecule can enter a cell and replicate there, autonomously (on its own) or after it has become integrated into a chromosome. (12 Dec 1998) |
| Tet DNA polymerase | <enzyme> From thermus thermophilus; thermostable, used as a replacement for taq polymerase in DNA sequencing Registry number: EC 2.7.7.- Synonym: DNA polymerase tet (26 Jun 1999) |
| transfer DNA | <molecular biology> The transforming region of DNA in the Ti plasmid of agrobacterium tumefaciens. Acronym: t-DNA (04 Jul 1999) |
| triple DNA | <molecular biology> A variation of DNA, in which there is a third strand of nucleotides binding to the first two by specific base pairing. (14 Nov 1997) |
