dna replication- lqc 4b

Question 1

step 1 of dna replication process

Answer 1

The enzyme DNA helicase breaks the hydrogen bonds between the two strands in the DNA molecule and the DNA strands separate

Question 2

step 2 of dna replication process

Answer 2

Both DNA strands act as templates (for formation of new DNA strands)

Question 3

step 3 of dna replication process

Answer 3

Free DNA mononucleotides line up along both DNA strands

Question 4

step 4 of dna replication process

Answer 4

Complementary base pairing between bases

Question 5

step 5 of dna replication process

Answer 5

Hydrogen bonds form between bases to join the two DNA strands

Question 6

step 6 of dna replication process

Answer 6

The enzyme DNA polymerase joins adjacent mononucleotides with phosphodiester bonds, in condensation reactions

Question 7

step 7 of dna replication process

Answer 7

This process is known as semi-conservative replication

Question 8

Role of DNA polymerase in DNA replication is to

Answer 8

act as an enzyme to join adjacent mononucleotides with phosphodiester bonds, in condensation reactions to form a new DNA strand
