Dna Replication

Question 1

What type of replication does DNA undergo?

Answer 1

DNA replication is semiconservative

This means that each new DNA molecule consists of one old strand and one newly synthesized strand.

Question 2

What does semiconservative DNA replication imply about the daughter strands?

Answer 2

Each daughter strand is part old, part new

This indicates that one strand is derived from the original DNA molecule.

Question 3

Which enzyme is responsible for unwinding and unzipping the DNA strand during replication?

Answer 3

The enzyme helicase

Helicase separates the two strands of DNA to allow replication.

Question 4

What role does the enzyme polymerase play in DNA replication?

Answer 4

Polymerase pairs nucleotides to the open side of each strand

This enzyme synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Question 5

Fill in the blank: DNA replication is _______.

Answer 5

semiconservative

Question 6

Answer 6

DNA replication is semiconservative

Question 7

What does semiconservative DNA replication imply about the daughter strands?

Answer 7
