Why does the gamete we are placing on
our punnett square have two different
letters?
Because we are crossing two traits,
therefore need two alleles.
~
Because it's a gamete, it will have half the
genetic information of the parent (1
allele) and because it's a dihybrid cross,
there is one allele for each trait.

Why are scientists concerned about the depletion of the ozone levels in the stratosphere?

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.

Hershey and chase confirmed that dna, not protein, was the genetic material. how do the results of their two experiments support this conclusion?
