Question

1. which enzyme unzips the dna at the beginning of replication? 6 points helicase dna polymerase iii dna polymerase i primase ligase 5. after unzipping the dna, rna primers are added so the process continues. what is the name of the enzyme that adds these rna primers? 6 points helicase dna polymerase iii dna polymerase i primase ligase

Explanation:

1. Helicase is the enzyme that unzips the DNA double - helix at the start of replication by breaking the hydrogen bonds between base pairs.
2. Primase is the enzyme that synthesizes short RNA primers which are needed for DNA polymerase to start adding nucleotides during DNA replication after the DNA has been unzipped.

Answer:

1. A. Helicase
2. D. Primase
