| single-strand break | A break in double-stranded DNA in which only one of the two strands has been cleaved; both strands have not separated from each other. (05 Mar 2000) |
|---|---|
| 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) |
| CD4-positive T-lymphocytes | A critical subpopulation of regulatory T-lymphocytes involved in the induction of most immunological functions. The HIV virus has selective tropism for the t4 cell which expresses the CD4 phenotypic marker, a receptor for HIV. In fact, the key element in the profound immunosuppression seen in HIV infection is the depletion of this subset of T-lymphocytes, which includes both the helper-inducer (T-lymphocytes, helper-inducer) and suppressor-inducer (T-lymphocytes, suppressor-inducer) T-cells. (12 Dec 1998) |
| CD8-positive T-lymphocytes | A critical subpopulation of regulatory T-lymphocytes involved in MHC class I-restricted interactions. They include both cytotoxic T-lymphocytes (T-lymphocytes, cytotoxic) and suppressor T-lymphocytes (T-lymphocytes, suppressor-effector). (12 Dec 1998) |
| gram-positive | <microbiology> Bacteria that retain the stain or that are resistant to decolourisation by alcohol during Gram's method of staining. This is a primary characteristic of bacteria whose cell wall is composed of a thick layer of peptidologlycan containing teichoic and lipoteichoic acid complexed to the peptidoglycan. See: gram-negative (06 Oct 1997) |
| gram-positive asporogenous rods | <microbiology> A gram-positive, non-spore-forming group of bacteria comprising organisms that have morphological and physiological characteristics in common. (12 Dec 1998) |
| gram-positive asporogenous rods, irregular | <microbiology> A group of irregular rod-shaped bacteria that stain gram-positive and do not produce endospores. (12 Dec 1998) |
| gram-positive asporogenous rods, regular | <microbiology> A group of regular rod-shaped bacteria that stain gram-positive and do not produce endospores. (12 Dec 1998) |
| gram-positive bacteria | <microbiology> Bacteria which retain the crystal violet stain when treated by gram's method. (12 Dec 1998) |
| gram-positive bacterial infections | <microbiology> Infections caused by bacteria that retain the crystal violet stain (positive) when treated by the gram-staining method. (12 Dec 1998) |
