Concept explainers
(a)
Interpretation:
The basis of inhibition of poly-A and RNA synthesis by cordycepin should be determined.
Concept introduction:
RNA synthesis (transcription) is the synthesis of an RNA molecule from the nucleotide’s adenine, cytosine, guanine, or uracil. The
(b)
Interpretation:
The reason for the high sensitivity of poly-A synthesis than other RNAs to cordycepin should be determined.
Concept introduction:
RNA synthesis (transcription) is the synthesis of an RNA molecule from the nucleotide’s adenine, cytosine, guanine, or uracil. The nucleotides are combined together by the enzyme RNA Polymerase.
(c)
Interpretation:
Whether the cordycepin is required to modify or not to exert its effect should be determined.
Concept introduction:
RNA synthesis (transcription) is the synthesis of an RNA molecule from the nucleotide’s adenine, cytosine, guanine, or uracil. The nucleotides are combined together by the enzyme RNA Polymerase.
