| LHD | lateral head displacement [sperm] |

| T4(D) | serum thyroxine measured by displacement analysis |
| minus strand | See: replicative form. (05 Mar 2000) |

| minus-strand nucleic acid | <molecular biology> An RNA or DNA strand which has the opposite sense of (would be complementary to) the mRNA of a virus. (12 Jan 1998) |
| coding strand | The strand of duplex DNA that has the same sequence as the mRNA (except that mRNA contains ribonucleotides instead of deoxyribonucleotides). Synonym: sense strand. (05 Mar 2000) |
| complementary strand | See: replicative form. (05 Mar 2000) |
| plus strand | See: replicative form. (05 Mar 2000) |
| positive strand RNA viruses | Class IV and VI viruses that have a single stranded RNA genome that can act as mRNA plus strand) and in which the virus RNA is itself infectious. Includes Picornaviridae, Togaviridae and Retroviridae. (18 Nov 1997) |
| c strand | <molecular biology> An abbreviation for the term complementary strand used of nucleic acids. (18 Nov 1997) |
| sense strand | <molecular biology> The strand of DNA which is used during transcription to make mRNA. The mRNA made thus has the sequence of the antisense strand of DNA, and it codes for a sense strand of polypeptide (which eventually becomes a protein or part of a protein) during translation. (09 Oct 1997) |
| h strand | <molecular biology> The strand of a double-stranded DNA molecule that is more buoyant than the other and floats at the top of a column when the dsDNA is denatured and put in an equilibrium centrifuge. (09 Oct 1997) |
| 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) |
| negative strand virus | A virus the genome of which is a strand of RNA that is complementary to messenger RNA; negative strand virus's also carry RNA polymerases necessary for the synthesis of messenger RNA. (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) |
