Question

1. list the steps of dna replication:

a. step 1:
b. step 2:
c. step 3:

Explanation:

• Step 1: Enzymes like helicase break hydrogen bonds between base pairs, separating the two strands of the DNA double helix.
• Step 2: Primase synthesizes RNA primers. DNA polymerase then adds nucleotides to the primers (leading strand is synthesized continuously, lagging strand as Okazaki fragments).
• Step 3: DNA polymerase proof - reads the new strands. Enzymes like ligase seal the nicks (in the lagging strand) and the replication process is terminated.

Answer:

a. Step 1: Unzipping of DNA double helix.
b. Step 2: Priming and synthesis of new strands.
c. Step 3: Termination and proof - reading.
