| strand | <geography> The shore, especially the beach of a sea, ocean, or large lake; rarely, the margin of a navigable river. Strand birds. <zoology> The brown hyena. Origin: AS. Strand; akin to D, G, Sw, & Dan. Strand, Icel. Strond. (26 Nov 1998) |
| nonsense strand | <molecular biology> DNA that does not code for part of a polypeptide chain or RNA.This includes introns and pseudo genes. In eukaryotes the majority of the DNA is noncoding. Noncoding strand refers to the so called nonsense strand, as opposed to the sense strand which is actually translated into mRNA. (18 Nov 1997) |
| double-strand break | A break in double-stranded DNA in which both strands have been cleaved; however, the two strands have not separated from each other. (05 Mar 2000) |
| lagging strand | The DNA strand that is replicated discontinuously from the 5' to the 3' direction. See: Okazaki fragments. Compare: leading strand. (09 Oct 1997) |
| four-strand crossing over | Crossing over with both strands of DNA from each sister chromatid, so that both strands from one chromatid are exchanged for both strands on the other. This is different from the usual case where only one of the two DNA strands on one sister chromatid is exchanged for the one matching strand (of the two strands) on the other sister chromatid. (09 Oct 1997) |
| leading strand | The DNA strand that is synthesised continuously during replication Compare: lagging strand. (09 Oct 1997) |
| 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 ascertainment | Method of ascertainment of locating affected individuals by hospital or clinic admission or another way in which probability of encountering the same family twice approaches zero; thus, the probability that a family will be ascertained is proportional to the number of affected members. (05 Mar 2000) |
| single-blind method | A method in which either the observer(s) or the subject(s) is kept ignorant of the group to which the subjects are assigned. (12 Dec 1998) |
| single bond | A covalent bond resulting from the sharing of one pair of electrons; e.g., H3C-CH3 (ethane). (05 Mar 2000) |
