Final answer:
In DNA replication, several proteins and enzymes are involved, including DNA polymerase, helicase, topoisomerase, and single-stranded binding proteins. They work together to facilitate the replication of DNA strands.
Step-by-step explanation:
DNA replication is a complex process that requires several proteins and enzymes. One of the key players is the DNA polymerase enzyme, which adds nucleotides to the growing DNA chain. Other proteins, such as helicase, topoisomerase, and single-stranded binding proteins, are also essential for DNA replication. Helicase unwinds the DNA strands at the replication fork, topoisomerase breaks and reforms the DNA structure, and single-stranded binding proteins keep the DNA strands separated. These proteins work together to ensure the smooth progression of DNA replication.
