Group of answer choices a 3'—TTAACGTCTAAGT—5' b 3'—UUAAGCUCUAAGU—5' c 5'—TTAACGTCTAAGT—3' d 5'—UUAAGCUCUAAGU—3'

Which of the following statements regarding DNA polymerases ineukaryotes is not correct?a. DNA polymerase α synthesizes a short RNA–DNA primer.b. DNA polymerases δ and ε synthesize most of the lagging and leading strands, respectively.c. Translesion-replicating DNA polymerases can replicate over damaged DNA.d. All of the above statements are correct.
Which of the following statements about DNA replication is INCORRECT? It is powered bythe hydrolysis of ATP. Each strand withinthe DNA double helix is used as a template for synthesis of a new strand. It requires that both strands of the double helix be separated from each other. It proceeds withthe addition of new nucleotides to the 3′ end of a growing DNA strand. It begins atmultiple origins of replication sites along eukaryotic chromosomes.
If a prokaryotic cell experienced a mutation that eliminated DNA polymerase's 3' to 5' exonuclease activity, what part of DNA synthesis would be affected? The single-stranded DNA would not remain open. The RNA primer could not be removed. The lagging strand fragments could not be connected together. The replication fork would be unable to move.
Which of the following statements BEST describes the process of DNA Replication? Group of answer choices The two strands of the parental molecule separate and serves as template for synthesis of a new strand. Each new strand is identical to its template strand. Each strand of both daughter molecules contains a mixture of old and newly synthesized DNA. The two parental strands reassociate after acting as templates for new strands restoring the parental double helix.
