Which of the following statements about DNA replication is true?

• A. DNA replication requires RNA polymerase.
• B. DNA replication occurs in the 5' to 3' direction.
• C. DNA replication is a conservative process.
• D. DNA replication is initiated at the telomeres.

Answer: (B)

Verified step by step guidance

1. Understand that DNA replication is the process by which a cell duplicates its DNA before cell division.
2. Recognize that DNA replication is semi-conservative, meaning each new DNA molecule consists of one original strand and one new strand.
3. Identify that DNA replication begins at specific locations in the genome called origins of replication, not at the telomeres.
4. Note that RNA polymerase is not involved in DNA replication; instead, DNA polymerase is the enzyme responsible for synthesizing new DNA strands.
5. Remember that DNA polymerase can only add nucleotides to the 3' end of a growing DNA strand, so DNA replication occurs in the 5' to 3' direction.
