Crick and Watson solved the structure of the DNA molecule by a. building models based on what others had learned about the properties of the molecule. Which of the following statements about DNA replication is NOT true. A helicase enzyme binds at the origin of replication and unwinds the two DNA strands, allowing DNA polymerase access to the single stranded templates. A primase synthesizes a short RNA molecule that provides a 3'OH for DNA synthesis to begin. DNA polymerase reads the template strand in a 3' to 5' direction, and the new, complementary daughter DNA strand is synthesized in the 5' to 3' direction.
Okazaki fragments form on both strands of the DNA at the replication fork.
The reason this does not lead to a high mutation frequency is because a. mispaired nucleotides cannot lead to mutations. RNA polymerase can distinguish between incorrectly paired nucleotides. I edits the new DNA duplex for mispairing. Which of the following statements concerning the polarity of DNA, RNA and protein synthesis is correct. DNA polymerase and RNA polymerase move along their template strands in a 3' to 5' direction.
