Expert Solution

41. Transcription actually begins in the +1 start site (Option C). Codon concept comes in the case of translation, origin of replication depicts the initiation of the replication, 5' cap is a post transcriptional modification and primer requires for t replication (So other options are wrong).

42. Usually Ribosomes mediate the process of translation (Option C). mRNA is the platform where ribosomes bind, ribosomal RNA don't play any kind of role, DNA Polymerase mediates the replication and RNA Polymerase mediates the transcription process. (So the other options are wrong).

43. The steps of transcription are respectively Initiation, Elongation and Termination. (Option C).'

44. Synthesis of product in Replication begins in Origin of Replication (Option A). +1 start site is associated with transcription, 5' Cap is a post transcriptional modification, Primer assists in Replication and Start Codon is associated with Translation. (So other options are wrong).

45. Primer directs or attracts the synthesis enzyme to the template in DNA Replication (Option C). 5' Cap and Poly A tail are post transcriptional modifications, Promoter is the binding place of RNA Polymerase in Transcription, Start Codon is associated with translation (So other options are wrong).

46. Phosphatase is not associated or involved in DNA Replication (Option D). DNA is involved in sealing the DNA Nick, Helicase is involved in the unwinding of the DNA, Primase is involved in synthesizing the primer and DNA Polymerase is involved in synthesizing the daughter strand from template strand in replication (So other options are wrong).

47.Amino acids are substrates for translation (Option A & C ). Ribonucleotides are involved in transcription and deoxy ribonucleotides are involved in Replication and phosphatase is an enzyme only (So the orher options are wrong).

48. Stop Codon helps in the termination of Translation (Option A). Run out of template never happens, End site is associated with ribosome, Terminator Sequence is associated with the termination of transcription and Poly A tail is a post transcriptional modification.

49.DNA replication is called semiconservative because half of the original duplex appears in the duplex formed in replication (Option C).

50. The product of translation is Protein (Option D). RNA is the product of transcription, amino acids are substrate of ranslation and ds DNA , ss DNA are product associated with Replication. (So other options are wrong).
