Question

Which statements are true

a. intrinsic termination in prokaryotes occurs when the rho termination factor interacts with the growing RNa transcript
b. 3 different RNA pol in eukaryotes transcribe different classes of genes
c. eukaryotic RNA pol II requires GTFs for initiation of transcription
d. since prokaryotes lack a nucleus, translation can begin before the transcription is fully transcribed

Answer 1

Intrinsic termination occurs when the rho termination factor interacts with the growing RNA transcript in prokaryotes. Eukaryotic RNA Polymerase II requires GTFs for the initiation of transcription. In prokaryotes, translation can begin before the transcription is fully transcribed, but in eukaryotes, simultaneous transcription and translation is not possible due to the presence of a nucleus.

Step-by-step explanation:

In prokaryotes, intrinsic termination occurs when the rho termination factor interacts with the growing RNA transcript. This termination process is independent of any specific termination signal in the DNA sequence. In eukaryotes, RNA Polymerase II requires General Transcription Factors (GTFs) for the initiation of transcription.

Additionally, in prokaryotes, translation can begin before the transcription is fully transcribed because there is no nucleus to separate the processes. However, in eukaryotes, the presence of a nucleus precludes simultaneous transcription and translation.
