Genetic Variation in the Expression of ADH in DROSOPHILA MELANOGASTER

Regulation of white locus expression: Vistes Lleer Editar Editar la fonte Ver historial. Abraham I, Doane WW. Abstract The white-apricot w a allele differs from the wild-type white gene by the presence of the retrovirus-like transposable element copia within the transcription unit.


Most RNAs derived from w a have 3′ termini within this insertion, and only small amounts of structurally normal RNA are produced. Second chromosomes, which also carry the structural gene Adhshow a great deal of polymorphism of genetic elements that determine how much enzyme protein accumulates. Estos individuos tienen niveles moderadamente altos fenilalanina en sangre.

Developmental expression of a regulatory gene is programmed at the level of splicing. The Drosophila melanogaster suppressor of Hairy-wing protein binds to specific sequences of the gypsy retrotransposon.

Characterization of Enhancer-of-White-Apricot in Drosophila Melanogaster

The evolution of mutation rates: In general, activities in the different organs and stages are highly correlated with one another. American Journal of Botany, Vol. Effects of transposable element insertions on RNA encoded by the white gene of Drosophila. National Center for Biotechnology InformationU. The activity of w a is reduced in trans by a semidominant mutation in the gene Enhancer-of-white-apricot E w a.

Evidence that a regulatory gene autoregulates splicing of its transcript. The effects on w a eye pigmentation of varying doses of the original E w a allele, the wild type allele, and the revertant alleles suggest that the original E w a allele produces a product that interferes with the activity of the wild type gene and that the revertants are null alleles.
