| direct terminal repeat | A particular sequence of nucleotides which appears on both ends of a DNA or RNA molecule. (09 Oct 1997) |

| inverted repeat | Either of two copies of a DNA sequence (such as those foundat oppositeends of a transposon) whichoccur in identical but inverted form. (09 Oct 1997) |
| trinucleotide repeat | <molecular biology> Repetitive part of a genome that may form part of the coding sequence of a gene. The length of such repeats is frequently polymorphic and unstably amplified repeats appear to be the major cause of such genetic diseases as Huntington disease, fragile X syndrome, spinobulbar muscular atrophy and myotonic dystrophy. (18 Nov 1997) |
| long-terminal repeat | <molecular biology> Identical DNA sequences, several hundred nucleotides long, found at either end of transposons and the proviral DNA, formed by reverse transcription of retroviral RNA. They are thought to have an essential role in integrating the transposon or provirus into the host DNA. Long terminal repeats have inverted repeats, that is, sequences close to either end are identical when read in opposite directions. In proviruses the upstream long-terminal repeat acts as a promoter and enhancer and the downstream long-terminal repeat as a polyadenylation site. Acronym: LTR (15 Nov 1997) |
