During DNA replication, the proteins that ensure denatured templates are not re- natured are called .........and the protein that connects the fragmented pieces of DNA in the lagging (discontinuous) strand is called......

Semi-conservative replication means (a) when DNA is replicated it consists one old strand and one new strand   (b) the strands are anti-parallel   (c) the strands are complementary   (d) A=T, G=C   (e) none of the above

The elongation of the leading strand during DNA synthesis(A) progresses away from the replication fork.(B) occurs in the 3′ S 5′ direction.(C) produces Okazaki fragments.(D) depends on the action of DNA polymerase

From which end of a strand of nucleic acid does DNA polymerase I REMOVE nucleotides? A) 5' B) 3' C) 2' D) N-term E) C-term

Does DNA replication follow the conservative,semiconservative, or dispersive model?

The first 15 bases of the original informational strand of DNA (which continues after what is shown) are 5-ATGAAACCCGGGTTT(...)-3'. Which of the following mutations to this original strand would lead to a frame shift? (Again, only the first 15 bases of the DNA strand are shown, even though they continue on.) Mutation #1: 5-ATGAAAGCCCGGGTT(...)-3' Mutation #2: 5-ATGAACCCCGGGTTT(...)-3' Mutation #3: 5-ATGAACCCGGGTTTA(...)-3'

What is the function of the single strand binding proteins during DNA replication?

The following diagram represents a DNA molecule that is undergoing replication. Draw in the strands of newly synthesized DNA and identify (a) the polarity of the newly synthesized strands, (b) the leading and lagging strands, (c) Okazaki fragments, and (d) RNA primers.

Which of the following statements is false about DNA replication? A) Each lagging strand of DNA is started by an RNA primer. B) DNA polymerase joins nucleotides in the 5' to 3' direction only. C) The leading strand of DNA is made continuously. D) More than one replication fork is present. E) A replication bubble opens in one direction only.

Number the steps of DNA replication in the correct order (1, 2, 3) a) ______ Polymerase travels down the DNA parent strand b)______ DNA strands are unzipped c) ______ Ligase binds Okazaki fragments together
