Flies Get a Head Start on Meiosis
Few distinctions in biology are as clearly drawn as the one between mitosis and meiosis. The function of mitosis is to produce two identical daughter cells, while the purpose of the first division of meiosis is to ensure the segregation of homologous chromosomes, and the second division is to create haploid gametes. These meiotic segregations usually rely on meiosis-specific processes such as t...
متن کاملEvolutionary Genetics: How Flies Get Naked
Researchers studying evolution of 'naked' (hairless) larval cuticle in Drosophila sechellia have discovered surprising complexity in the pattern of cis-regulatory differences that differentiate this species from its 'hairy' ancestors.

متن کاملSpindle Regulation: Mps1 Flies into New Areas
Analysis of a mutation in the Drosophila Mps1 ortholog further demonstrates the universality of Mps1 function in the spindle checkpoint, but suggests Mps1 function in centrosome duplication might not be so conserved. The work also contributes new additions to a list of Mps1 functions that continues to grow with each new study.
متن کاملTransposition: Mobile introns get into line
Group II introns encode highly structured, frequently self-splicing RNAs; they are also mobile genetic elements. This mobility has been found to involve DNA-primed reverse transcription, with similarities to retrotransposition and telomere maintenance.
