Comments
	The spatial and temporal expression patterns of fifteen families of retrotransposons are analysed during embryogenesis and are found to be conserved. Results suggest that all families carry cis-acting elements that control their spatial and temporal expression patterns. (Ding and Lipshitz, 1994) Progeny derived from w^a/w^a4 heterozygotes demonstrate that ectopic recombination between paired 3S18 elements produces duplications and deficiencies. (Lim and Simmons, 1994) Sequences homologous to 3S18 are present about 25 times in the Drosophila genome. (Goldberg et al., 1983) A retroviral-like transposable element. Described as an insertion associated with the w^a4 mutation by Goldberg et al. (FBrf0040134) (as BEL), and as an insertion within the non-transcribed spacer of an rDNA repeat by Bell et al. (FBrf0043377) and Fabijanski and Pellegrini (FBrf0038558). In situ hybridization experiments indicate that 3S18 elements are located at about twenty-five sites throughout the genome and that their distribution differs from one strain to another. The ends of this element hybridize to each other.
