Question

choose the correct order of proteins that function in the initiation, elongation, and termination stages of dna replication. question 30 options: a) dnaa, dna polymerase iii, dna polymerase i, dna ligase b) dnaa, dna polymerase i, dna polymerase iii, dna ligase c) dna polymerase iii, dna polymerase i, dna ligase, dnaa d) dna polymerase i, dnaa, dna polymerase iii, dna ligase

Answer 1

The correct order of proteins in DNA replication includes helicase, single-strand binding proteins, primase, d) DNA polymerase III, DNA polymerase I, and DNA ligase.

Step-by-step explanation:

The correct order of proteins that function in the initiation, elongation, and termination stages of DNA replication is:

1. Helicase: Separates the DNA strands at the origin of replication.
2. Single-strand binding proteins: Prevents reformation of DNA.
3. Primase: Synthesizes RNA primers complementary to the DNA strand.
4. DNA polymerase III: Adds nucleotides to the 3'-OH end of the primer, elongating the DNA strand.
5. DNA polymerase I: Fills gaps left by RNA primers with DNA nucleotides.
6. DNA ligase: Seals the gap between two DNA fragments by forming phosphodiester bonds.
