Question

What is/are the universal feature(s) of DNA replication?Choose all that apply.

	continuous replication of both strands of the double helix
	polymerization of a new strand in the 5' to 3' direction
	basepairing between nitrogenous bases
	semi-conservative replication
	release of PPi from incorporated nucleotides
	use of DNA primer to begin fragments

Match the name of the protein/enzyme with its correct function during replication.

You may use choices more than once or not at all.

scan for errors in newly synthesized DNA strand covalently link two DNA fragments together polymerize DNA nucleotides into fragments or entire strands disrupt basepairs between paired nucleotides remove supercoiling strain from DNA double helix polymerize RNA nucleotides into short fragment open up replication fork

1. helicase 2. primase 3. ligase 4. DNA polymerase 5. topoisomerase

I am totally not sure how to answer yet.

Answer 1

Answer:1,3 and 4 are true regarding the universal features of DNA.

Answer;a-4 DNA polymerase :It replaces the missing sections with correct nucleotides and the enzyme DNA ligase seals the gap.

b-3 DNA ligase:It facilitates the joining of DNA strands together by catalyzing the formation of a phosphodiester bond.

c-1-DNA helicase

DNA helicase continous to unwind the DNA forming a structure called the replication fork .The process of breaking the hydrogen bonds between the nucleotide base pairs in double stranded DNA requires energy.

d-

e-Topoisomerase

f-Primase

g-DNA helicase
