Total nucleic acids are extracted from a culture of animal cells and are then mixed with resin beads to which the polynucleotide 5′--3′ has been covalently attached. After a short incubation, the beads are then extracted from the mixture. When you analyze the cellular nucleic acids that have stuck to the beads, which of the following is most abundant?A. DNA.
B. tRNA.
C. rRNA. (it is not this one, I put this and it was wrong.)
D. mRNA.
E. Primary transcript RNA.

Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offspring. an incomplete dominance cross is performed between a bird that is homozygous for red feathers and a bird that is homozygous for blue feathers. purple offspring result. then, two of the purple offspring are crossed. according to the punnett square for this cross, how many of the offspring from the second cross will have a feather color that results from incomplete dominance? 1 in 4 2 in 4 3 in 4 4 in 4
