| P element | <molecular biology> A class of Drosophila transposon, widely used as a vector for reporter genes, for efficient germ line transformation and for enhancer trap or insertional mutagenesis studies. (18 Nov 1997) |
| mobile genetic element | <molecular biology> Small, mobile DNA sequences that can replicate and insert copies at random sites within chromosomes. They have nearly identical sequences at each end, oppositely oriented (inverted) repeats and code for the enzyme, transposase, that catalyses their insertion. Bacteria have two types of transposon, simple transposons that have only the genes needed for insertion and complex transposons that contain genes in addition to those needed for insertion. Eukaryotes contain two classes of mobile genetic elements, the first are like bacterial transposons in that DNA sequences move directly. The second class (retrotransposons) move by producing RNA that is transcribed, by reverse transcriptase, into DNA which is then inserted at a new site. (13 Nov 1997) |
| picture element | <microscopy> Any segment of a video scan line whose dimension along the line is equal to the line spacing. (05 Aug 1998) |
