Total questions: 10
Worksheet time: 6mins
What is step 1 of replication?
Nucleotides are added to the exposed bases on the DNA molecule
The DNA molecule is unwound
Nucleotides are broken off of the DNA molecule
1 strand of the original DNA molecule is conserved in the new molecules
What is step 2 of DNA replication?
The DNA molecule is unzipped (hydrogen bonds are broken)
Nucleotides are added to two template strands of DNA according to base-pairing rules
Complementary strands are added to the template strands by DNA helicase
What is step 3 of DNA replication
DNA is wound to form a double helix once more
Free-floating nucleotides are added to the exposed bases on each template strand
DNA is unzipped
What is step 4 of DNA replication?
DNA is unzipped
Nucleotides are added to the exposed bases
DNA is unwound
2 identical strands of DNA are formed
What is the enzyme responsible for the unwinding and unzipping of the DNA molecule during replication?
DNA polymerase
DNA ligase
DNA primase
DNA helicase
Which enzyme is responsible for adding nucleotides to the exposed bases during DNA replication?
DNA ligase
DNA primase
DNA polymerase
DNA helicase
CAT TCA CTG
The new DNA strand formed after DNA replication is an exact copy of its parent strand
True
False
The old strand is "conserved" and used to make the new strands
