Partial revertants of the transposable element-associated suppressible allele white-apricot in Drosophila melanogaster: Gene regulation in adaptive evolution. We have also found evidence of third-chromosome elements that affect the level of ADH. Journal List Genetics v. 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.

Environmental factors affecting the quantity of alcohol dehydrogenase in Drosophila melanogaster. In Modern Genetic Analysis. The contribution of ecological genetics to evolutionary theory: Drosophila melanogaster mutations suppressible by the suppressor of Hairy-wing are insertions of a 7. Effects of transposable element insertions on RNA encoded by the white gene melanogastre Drosophila. Articles from Genetics are provided here courtesy of Genetics Society of America.

Second chromosomes, which also carry the structural gene Adhshow a great deal of polymorphism of genetic elements that determine how much enzyme protein accumulates.

Abstract Several chromosomes derived from natural populations have been identified that affect the expression of alcohol dehydrogenase ADH. We propose that the E w a gene product influences the activity mutacionez the downstream copia long terminal repeat in 3′ end formation. Please review our privacy policy.

N Engl J Med. The level of enzyme was measured in third instar larvae, 6-today-old males and in larval fat bodies and alimentary canals.

One line was found, however, in which the ADH level in the fat body is more than twice the level one would expect on the basis of the activity in alimentary canal.

La mayor parte de la evidencia indica que tal desenvolvimientu arreya un procesu de dellos pasos secuenciales nos cualos asoceden alteraciones en dellos, frecuentemente munchos, d’estos xenes.

Limits to Adaptation in asexual populations. Sequence of a cDNA from the Drosophila melanogaster white gene. Most RNAs derived from w a have 3′ termini within this insertion, and only small amounts of structurally normal RNA are produced. DNA sequence of the white locus of Drosophila melanogaster. Several chromosomes derived from natural populations have been identified that affect the expression of alcohol dehydrogenase ADH. The economics of mutation. 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.
