For each statement below, indicate if it is referring to DNA, RNA, or both

• Both

• Are nucleic acid and made of nucleotide

• DNA

• involves in the process of making protein.

• RNA

•

Match the following enzymes to their roles in DNA replication.

• "Glue" the two strands together.

Which is the order of replication?

• 3, 2, 1, 4
• 2, 1, 4, 3
• 2, 3, 1, 4
• 3, 4, 1, 2

Answer explanation

#1 break the h-bonds between the bases.

#2 after adding a primer, build each new strand by using the template strand and following complimentary base pairing.

#3 voila! We end up with two identical DNA strands which are semiconservative.

If a DNA molecule is 18% Guanine which of the following is correct?

• 18% cytosine, 32% adenine, 32% thymine
• 32% cytosine, 18% adenine, 32% thymine
• 18% cytosine, 64% adenine, 64% thymine
• 32% cytosine, 32% adenine, 18% thymine

Answer explanation

18% G = 18% C (36% total)

32% A = 32% T (64%total)
