| RNA, double-stranded | RNA consisting of two strands as opposed to the more prevalent single-stranded RNA. most of the double-stranded segments are formed from transcription of DNA by intramolecular base-pairing of inverted complementary sequences separated by a single-stranded loop. Some double-stranded segments of RNA are normal in all organisms. (12 Dec 1998) |

| polymorphism, single-stranded conformational | Variation occurring within a species in the conformation of denatured DNA fragments. These single-stranded DNA fragments are allowed to partially renature in a way that prevents the formation of double-stranded DNA. The fragments are run on polyacrylamide gels under various conditions to detect subtle changes in migration due to altered secondary structure. The resulting bands will align themselves if the fragments are the same, but will misalign if any point mutations are present. Sscps have been used in detecting mutations in various genes, such as oncogenes, tumour suppressor genes, and genes responsible for genetic diseases. (12 Dec 1998) |
| single stranded binding protein | <protein> SSB's are proteins responsiblefor holding the replication fork of DNAopen while polymerases readthe templates. (09 Oct 1997) |
| single stranded conformational polymorphism | Technique for detecting point mutations in genes by amplifying a region of genomic DNA (using asymmetric PCR) and running the resulting product on a high quality gel. Single base substitutions can alter the secondary structure of the fragment in the gel, producing a visible shift in its mobility. (18 Nov 1997) |
| single stranded DNA | <molecular biology> DNA that consists of only one chain of nucleotides rather than the two base pairing strands found in DNA in the double helix form. Parvoviridae have a single stranded DNA genome. Single stranded DNA can be produced experimentally by rapidly cooling heat denatured DNA. Heating causes the strands to separate and rapid cooling prevents renaturation. (18 Nov 1997) |
| single stranded DNA dependent ATPase | <enzyme> Probably involved in DNA replication Registry number: EC 3.6.1.- Synonym: ssdna-dependent atpase (26 Jun 1999) |
| negative stranded RNA virus | <virology> Class V viruses that have an RNA genome that is complementary to the mRNA, the positive strand. They also carry the virus specific RNA polymerase necessary for the synthesis of the mRNA. Includes (Rhabdoviridae, Paramyxoviridae and Myoviridae (for example the T even phages). (18 Nov 1997) |
| DNA, single-stranded | A single chain of deoxyribonucleotides that occurs in some bacteria and viruses. It usually exists as a covalently closed circle. (12 Dec 1998) |
| double-stranded complimentary DNA | <molecular biology> A duplex DNA molecule copied from a copy DNA template. (09 Oct 1997) |
| stranded | with the bottom lodged on a reef or shoal in shallow water |
