Question

what are the short sections formed on the lagging strand during dna replication called?
a. leading fragments
b. helicase fragments
c. okazaki fragments
d. polymerase fragments
which enzyme detects and corrects errors during dna replication?
a. proofreading enzymes in dna polymerases
b. helicase
c. ligase
d. rna polymerase
what happens during the termination phase of dna replication?
a. new dna strands are synthesized
b. dna strands are unwound
c. nucleotides are added to the growing strand
d. specific sequences signal the completion of replication

Explanation:

1. During DNA replication, the short - sections formed on the lagging strand are Okazaki fragments. Leading strand is synthesized continuously, and there are no such things as helicase or polymerase fragments in this context.
2. DNA polymerases have proofreading enzymes that detect and correct errors during DNA replication. Helicase unwinds DNA, ligase joins DNA fragments, and RNA polymerase is involved in transcription.
3. In the termination phase of DNA replication, specific sequences signal the completion of replication. New DNA strand synthesis and nucleotide addition occur during the elongation phase, and DNA strand unwinding occurs during the initiation phase.

Answer:

1. c. Okazaki fragments
2. a. Proofreading enzymes in DNA polymerases
3. d. Specific sequences signal the completion of replication
