Introduction :- Replication is the process of synthesis of the DNA molecule . It occurs in S ( Synthesis) phase of the cell cycle . In replication , new DNA strands are synthesized by using old or parental as the template strand. Transcription is the process of synthesis of different types of RNA molecules like mRNA , tRNA , ribosomal RNA , snRNA etc , from the DNA molecule .Answer :- Option a), Polymerases that synthesize in the 5' → 3' direction and option d), Both processes require enzymes with helicase activity , are the correct option because thes are similar characteristics shared between DNA replication and transcription . Explanation for correct option a) and d) :- Option a), Polymerases that synthesize in the 5' → 3' direction is correct option because during DNA replication , the DNA polymerase enzyme synthesize the new DNA strands in the 5'-3' direction and in case of transcription , the DNA dependent RNA polymerase synthesize RNA strand in 5'-3' direction. Option d) , both processes require enzymes with helicase activity ,is correct because for both DNA replication and transcription to occur , unwinding of double stranded DNA helix is required . And we know that DNA is used as a template for both DNA replication and transcription . So enzymes with helicase property is required in both of these processes. Explanation for incorrect option b) , c) and e) :- option b) Simultaneous synthesis of two complementary nucleic acid strands , is incorrect because this occurs only in DNA replication but not in the transcription. In transcription process , only single strand of DNA is used as a template while in DNA replication, both strands are used ( lagging strand and leading strand). Option c) , Complementary base-pairing of nucleotides using a single-stranded DNA template , is incorrect because this statement is the characteristics feature of only transcription but not the DNA replication . Single strand DNA is used as a template in transcription only . In DNA replication, both of the strands are used as the template . Option e) , A-U and C-G base-pairing , is incorrect because this occurs in the transcription (RNA synthesis) only but not in the DNA replication. In DNA replication , adenine forms base pairing with thymine but in case of transcription, adenine forms base pairing with Uracil .
