Adenine (a) cytosine (c) guanine (g) thymine (t) uracil (u) dna can make exact copies of itself through replication because the nitrogen bases always pair a) a-t and c-g. b) a-u and c-g. c) a-c and t-g. d) c-g and t-u.

dna damages cause changes in the structure of the genetic material and prevents the replication mechanism from functioning and performing properly. dna damage and mutation have different biological consequences. while most dna damages can undergo dna repair, such repair is not 100% efficient.

the framers of the constitution insisted that federal judges be nominated instead of elected due to their desire to have judges above the shifting whims of the masses.

the hope, whether achieved or not, was that federal judges would only be beholden to the law and that by not having judges be elected, they would be protected if that law dictated an outcome that ran counter to popular opinion.
