Question

Question 2

Which of the following is TRUE about transcription (transcription specifically, not translation)?

It creates tRNA.

It creates DNA.

It creates protein.

Only 1 gene (not the whole chromosome) is transcribed each time.

Answer 1

True statements about transcription:

•It creates tRNA

mRNA, tRNA,rRNA all are produced by transcription.

RNA polymerase III catalyzes the synthesis of tRNA.

RNA polymerase II catalyzes the synthesis of mRNA

RNA polymerase I catalyzes the synthesis of rRNA.

•Only 1 gene (not the whole chromosome) is transcribed each time unlike in replication where the total DNA gets duplicated.

False statements:

•Transcription is the synthesis of RNA from DNA and not the synthesis of DNA.

•Transcription doesn't create proteins.A process called translation synthesizes proteins from RNA.

Hence the first and last options are correct.
