In a flowering plant, gene "A" encodes an enzyme responsible for the presence of dots on the flowers’ petals. A1, A2, and A3 are the three known alleles of this gene; A1 is the wild type, A2 is a null allele that makes no product, while A3 has a mutation in the promoter region of the gene, which results in the synthesis of very little gene product. If the "A" gene is haploinsufficient, what is the predicted phenotypic ratio in the F1 of a cross between a wild type and a A2/A3 heterozygous?

The dna in a cell’s nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well as proteins that are targeted for secretion from the cell. for example, consider these two proteins: phosphofructokinase (pfk) is an enzyme that functions in the cytoplasm during glycolysis. insulin, a protein that regulates blood sugar levels, is secreted from specialized pancreatic cells. assume that you can track the cellular locations of these two proteins from the time that translation is complete until the proteins reach their final destinations. for each protein, identify its targeting pathway: the sequence of cellular locations in which the protein is found from when translation is complete until it reaches its final (functional) destination. (note that if an organelle is listed in a pathway, the location implied is inside the organelle, not in the membrane that surrounds the organelle.)
