Name the protein complex that stabilizes the separated strand of DNA during replication:
Correct answer: C. Single-stranded binding proteins
- A. Double Stranded binding proteins
- B. Double-stranded binding enzymes
- C. Single-stranded binding proteins
- D. Single-stranded binding enzyme
Explanation
Single-stranded (SSBs) are proteins that bind to single-stranded DNA during processes such as DNA replication and repair. They stabilize the unwound DNA strands, preventing them from re-annealing or forming secondary structures. By keeping the strands separate, SSBs allow other enzymes, like DNA polymerases, to access the DNA for replication and repair.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
