Final answer:
Single-stranded binding proteins (SSBs) prevent the rejoining of DNA strands during replication, allowing other enzymes to access the DNA strands and carry out replication.
Step-by-step explanation:
DNA replication involves the process of unwinding the DNA double helix and synthesizing new strands. The DNA strands need to be kept apart during replication, and this is where single-stranded binding proteins (SSBs) come in. SSBs bind to the single-stranded DNA and prevent them from rejoining, allowing other enzymes to access the DNA strands and carry out replication. This ensures that the DNA replication process proceeds smoothly.
