WebQuestion: Wild-type Drosophila Bithorax mutant 1. The mutation resulting in the bithorax phenotype above is due to loss of expression of the ubx gene. Ubx protein acts as a transcriptional repressor and suppresses development of a wing within a region of the thorax (the third thorax segment). The ubx gene was sequenced in the mutants to ... The Bithorax complex (BX-C) is one of two Drosophila melanogaster homeotic gene complexes, located on the right arm of chromosome 3. It is responsible for the differentiation of the posterior two-thirds (posterior thorax and each abdominal segment) of the fly by the regulation of three genes within the … See more The first homeotic mutation to be isolated was the bithorax (bx) mutant in 1915 by Calvin Bridges, which was later worked on and better characterized as a gene cluster by Edward B. Lewis. Lewis found that BX-C contained genes … See more The gene complex is located on the right arm of chromosome 3 alongside the other homeotic gene complex, the Antennapedia (Antp) complex. It is over 300 kb long and contains nine … See more BX-C controls the differential patterning of the posterior thoracic segment (T3) and all 8 of the abdominal segments (A1-A8) of Drosophila.

WebA model for precise and responsive transcriptional regulation. The regulation of the Drosophila melanogaster Antennapedia (ANT-C) and bithorax (BX-C) clusters of homeotic genes provide a classic example of the critical need for precise transcription regulation. During early embryogenesis, expression of the genes within the ANT-C and BX-C dictate … WebOct 8, 2016 · A trithorax-like gene is interrupted by chromosome 11q23 translocations in acute leukaemias.
