C16. The structure and function of DNA helicase and ρ protein are rather similar to each other. Explain how the functions of these two proteins are similar and how they are different.
Both DNA helicase and ρ protein break the hydrogen bonds of the DNA and move 5’ to 3’. They are different in that DNA helicase moves along the DNA and is used for DNA replication while ρ protein moves along the RNA and is used to promote transcriptional termination.
