Verified step by step guidance
1
Understand the role of proteins in DNA replication: DNA replication involves several key proteins that help in unwinding the DNA, synthesizing new strands, and joining fragments.
Identify the function of DNA polymerase: DNA polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides complementary to the template strand.
Identify the function of ligase: Ligase is an enzyme that joins Okazaki fragments on the lagging strand, sealing nicks in the sugar-phosphate backbone of DNA.
Identify the function of helicase: Helicase is an enzyme that unwinds the DNA double helix, separating the two strands to allow replication to occur.
Recognize the role of ribosomes: Ribosomes are not involved in DNA replication; they are the cellular machinery responsible for protein synthesis during translation, not DNA replication.
