Verified step by step guidance

Understand the process of DNA replication: DNA replication is the process by which a cell duplicates its DNA, creating two identical copies. This process is essential for cell division.
Identify the key components involved in DNA replication: These include DNA polymerase, helicase, primase, ligase, and RNA primers, among others.
Recognize the role of RNA primers: RNA primers are short sequences of RNA nucleotides that provide a starting point for DNA polymerase to begin synthesis of the new DNA strand.
Differentiate between the options given: Ribosomes are involved in protein synthesis, not DNA replication. Messenger RNA (mRNA) is involved in transcription and translation, not directly in DNA replication. Proteases are enzymes that break down proteins, not involved in DNA replication. Ligase is involved in joining Okazaki fragments on the lagging strand during DNA replication.
Conclude that RNA primers are essential for initiating DNA synthesis, making them a required component for DNA replication.
