Nmice, black fur (b) is dominant to white (b) . at different locus, a dominant allele (a) produces a band of yellow just below the tip of each hair in mice that have black fur, which gives a frosted appearance that is termed agouti. expression of the recessive (a) allele results in a solid coat color. if double heterozygous agouti parents are crossed, what color will most of the offspring be ?

One function of the poly-a tail on eukaryotic mrna sequences is to the mrna be transported from the nucleus to the cytoplasm. prokaryotic mrna also has a poly-a tail. choose the best explanation of the prokaryotic poly-a tail. a. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails. b. prokaryotic poly-a tails have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species. c. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails have other functions,because prokaryotes don't have nuclei.
