DNA - Replication

Question 1

making copies

Answer 1

• before a cell divides, it duplicates its DNA in a copying process called replication

Question 2

templates

Answer 2

• the double helix structure of DNA explained how it could be replicated
• each strand of the DNA has all the information needed to construct the other half due to base pairing
• during replication the ladder is broken in half and all that needs to be done is to rebuild the halves that are no longer attached

Question 3

steps of replication

Answer 3

• DNA molecule separates into two strands
• forming replication forks
• produces two new complementary strands following the rules of base pairing
• each strand of the double helix serves as a template for the new strand

Question 4

enzymes at work

Answer 4

• DNA polymerase the principal enzymer involved in DNA replication
• polymer- DNA is a polymer
• ase = enzyme
• its job is to join individual nucleotides to produce the DNA molecule
• it also proofreads each new DNA strand
