Question-3

In eukaryotic cell transcription, RNA splicing and RNA capping take place inside the

(a) nucleus

(b) ribosomes

(c) dictyosomes

(d) ER

Question-4

If the gene encoding the lac repressor is mutated so that it can no longer bind the operator, will transcription of that operon occur?

(a) Yes, because the operator will not be bound by repressor and RNA polymerase can transcribe the lac operon.

(b) No, because RNA polymerase is need to transcribe the genes.

(c) Yes, but only when lactose is present.

(d) No, because cAMP levels are low when the repressor is nonfunctional.

(a) Ribonucleotides

(b) Nucleotides

(c) Nucleosides

(d) Deoxyribonucleotides
