Answer 2

epsilon

Question 3

Eukaryotic DNA polymerases: ___ replicates mt DNA.

Answer 3

gamma

Question 4

Eukaryotic DNA polymerases: __ is similar to prokaryotic DNA polymerase II in that they and are involved in repair and recombination; but neither are involved in replication.

Answer 4

Beta

Question 5

Eukaryotic DNA polymerases: ___ is a hybrid RNA/DNA polymerase. It has primase activity for the primer, then lays a short sequence of DNA nucleotides.

Answer 5

alpha

Question 6

Eukaryotic DNA polymerases: __ starts the job by laying down a primer and a few DNA nucleotides. __ helps elongation in some kind of way, but it seems minor. __ is the finisher. [AED]

Answer 6

alpha; elipson; delta

Question 7

These introns are self-splicing; found in some rRNA, including mitochondria; fungi, protozoans, and a few viruses.

Answer 7

Group I

Question 8

These introns are self-splicing, are usually found in mitochondria, and uses a method of splicing very similar to a spliceosome-mediated process.

Answer 8

Group II

Question 9

These introns are self-splicing; but their method requires small ribonucleoprotein particles, snRNAs, and a spliceosome.

Answer 9

nuclear pre-mRNA introns
