Verified step by step guidance

Understand the process of DNA replication: DNA replication is the process by which a cell duplicates its DNA, usually before cell division. It involves unwinding the DNA double helix and synthesizing a new strand complementary to each original strand.
Identify the key enzymes involved in DNA replication: The main enzyme responsible for synthesizing new DNA strands is DNA polymerase. It adds nucleotides to the growing DNA strand in a sequence complementary to the template strand.
Differentiate between DNA replication and RNA functions: Messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA) are involved in protein synthesis, not DNA replication. mRNA carries genetic information from DNA to the ribosome, rRNA is a component of ribosomes, and tRNA brings amino acids to the ribosome during translation.
Recognize the role of DNA polymerase: DNA polymerase is crucial for DNA replication as it catalyzes the addition of nucleotides to the new DNA strand, ensuring accurate copying of the genetic material.
Conclude which molecule is directly involved in DNA replication: Based on the roles of the molecules listed, DNA polymerase is the enzyme that directly participates in the DNA replication process.
