DNA replication

Question 1

When and why does this process occur in cells?

Answer 1

DNA replication creates a new, identical copy of DNA. Dna strand doubles

Occurs in synthesis

Question 2

Identify the role or helicase and DNA polymerase

Answer 2

an enzyme called a DNA helicase separates the two strands of the DNA double helix, by breaking the hydrogen bonds.

DNA polymerases attached new nucleotides to build a complementary strand.

Question 3

Explain the term semi-conservative

Answer 3

This process is known as semi-conservative replication because two copies of the original DNA molecule are produced, each copy conserving (replicating) the information from one half of the original DNA molecule.

Question 4

What is the name of the original strands of DNA?

Answer 4

Parent strands

Question 5

What is the name of the new strand?

Answer 5

Daughter strands

Question 6

What is produced at the end of the process of DNA replication?

Answer 6

The result is 2 DNA molecules that each consist of one new and one old strand of DNA.
