(a) three different rna polymerases in eukaryotes transcribe different classes of genes.
(b) since prokaryotes lack a nucleus, translation can begin before the transcript is fully transcribed.
(c) intrinsic termination in prokaryotes occurs when the rho termination factor interacts with the growing rna transcript.
(d) eukaryotic rna polymerase ii requires general transcription factors for initiation of transcription.

A. B. D.

Explanation:

(A) Three different RNA polymerases in eukaryotes transcribe different classes of genes. TRUE (The eukaryotes are more evolved organisms than prokaryotes and their genome is larger, therefore their processes are more complex)

(B) Since prokaryotes lack a nucleus, translation can begin before the transcript is fully transcribed.TRUE (because there are not barriers that separate both processes, plus they occur in the same direction 5 'to 3'.

(C) Intrinsic termination in prokaryotes occurs when the rho termination factor interacts with the growing RNA transcript. FALSE ( in bacteria, there are two termination types: rho-dependent and rho-independent)

(D) Eukaryotic RNA polymerase II requires general transcription factors for initiation of transcription. TRUE (The general transcription factors bind with the RNA polymerase II to form a complex that surrounds the starting point, and determine the site of initiation)
