If primase makes an error and incorporates an incorrect base in the nucleic acid primer, then why would this not be a problem given the DNA replication mechanism? O Primase only copies end sequences that will be protected by telomers The lagging strand utilizes a helicase to prevent replication errors O Primase can be error proofed using a domain of DNA polymerase O The RNA primer sequence is removed and not used as a template

What does i mean to say that extension by DNA polymerase III proceeds 5' 3'? The 5' end of a DNA polymerase molecule attaches to the 3' end of primase. DNA polymerase adds nucleotides to a growing strand, moving in the 5'-3' direction. O DNA polymerase seals nicks as it moves along a DNA strand toward the 3' end. DNA polymerase can only synthesize DNA at the 5' end of an existing strand of DNA. O O 0
