Induced Loss of a Ring and a Telomeric Chromosome in Drosophila Melanogaster.
ING chromosomes are potentially useful for studying the process of rejoining R after chromosome breakage, since a certain portion of the restitutions should produce dicentric ring chromosomes or interlocked rings rather than structurally normal chromosomes. The relevance of ring chromosomes studies to problems of induced chromosome breakage in Drosophila melanogaster sperm has been recognized f...
متن کاملPositive selection at the binding sites of the male-specific lethal complex involved in dosage compensation in Drosophila.
In many taxa, males and females differ with respect to their sex chromosomes, and dosage compensation mechanisms have evolved to equalize X-linked gene transcription. In Drosophila, the male-specific lethal (MSL) complex binds to hundreds of sites along the male X chromosome and mediates twofold hypertranscription of the single male X. Two recent studies found evidence for lineage-specific adap...
متن کاملConcentration dependent effect of morphine, aspirin, capsaicin and chili pepper hydro alcoholic extract on thermal and chemical pain model in fruit fly (Drosophila melanogaster)
Introduction: Pain research using animal models is related to ethical concerns, so invertebrates and insects have been recommended by researchers. In the present study, the nociceptive and antinociceptive effects of capsaicin, aspirin, morphine and chili extract were examined using fruit fly (Drosophila melanogaster) as an alternative for rodent pain model. Methods: Stage 3 of larvae and ad...
متن کاملChromosome Segregation in Drosophila Virilis Males with Multiple Sex Chromosomes.
NE of the many puzzling aspects of chromosome mechanics is the process of 0 pairing of homologous chromosomes and their disjunction a t the first meiotic division. A genetic indication of the intimacy of pairing is the amount of exchange taking place between homologous chromosomes. Where more than two chromosomes share homologies, as in translocation heterozygotes, the correlation between excha...
متن کاملToxicological Evaluation of a New Lepidopteran Insecticide, Flubendiamide, in Non-Target Drosophila melanogaster Meigen (Diptera: Drosophilidae)
Background: Flubendiamide, comparatively a new pesticide designed to eradicate lepidopteran insect pests is known to have low risk to birds, mammals, fish, algae, honey bees, non-target arthropods, earthworms, soil macro- and micro-organisms, non-target plants as well as sewage treatment organisms; however, the risk assessment for aquatic invertebrates from metabolite could not be finalized wit...
