Question

(03.02 lc)
which of the following is a complementary base pair for dna?
a adenine and cytosine
b guanine and cytosine
c adenine and guanine
d cytosine and thymine

question 2 (4 points)
(03.02 mc)
the dna structures of prokaryotic and eukaryotic cells share similarities and differences. one way in which they are the same is that
a both have sugar - phosphate backbones
b most of the dna is in the form of plasmids
c both have a singular circular chromosome
d the dna is packaged into several linear pieces

Explanation:

1. In DNA, the complementary base - pairing rules are adenine (A) with thymine (T) and guanine (G) with cytosine (C). So for the first question, guanine and cytosine is a correct complementary base pair.
2. For prokaryotic and eukaryotic DNA, both have a sugar - phosphate backbone. Prokaryotes often have circular DNA and plasmids, while eukaryotes have linear chromosomes.

Answer:

Question 1: b. Guanine and cytosine
Question 2: a. both have sugar - phosphate backbones
