1.) A certain Drosophila protein-coding gene has one intron. If a large sample of null alleles (null alleles are mutations that destroy the function of the protein) of this gene are examined, will any of the mutant sites be expected in thea) exons?b) introns?c) promoter?d) intron-exon boundary?Please justify your answers. […]
Please answer these questions on a separate sheet(s) of paper, and please type.Small, handwritten figures on an otherwise typed document are acceptable. It is imperative that no part of your answer be copied directly from an online source, or from another student, either in this class or from a previous […]
Inversions are known to affect crossing over. The following homologs have the indicated gene order (the filled and open circles are homologous centromeres): filled ABCDE open ADCBE A) considering the position of the centromere, what is this sort of inversion called? B) diagram the alignment of these chromosomes during meiosis. […]
Calculate the free energy change of pumping Ca+2 from the cytosol, where its concentration is about 1.0 x 10-7 M, to the extracellular fluid, where its concentration is about 1.0 mM. Assume a temperature of 37oC and a transmembrane potential of 50 mV (inside more negative) for the plasma membrane. Calculate the […]
