Answer 1

Q. A(n) _____ is located upstream of a gene's coding region.

Ans. The correct option is a). promoter.

Promoter is the sequence where RNA polymerase binds and start transcription of a gene. It is located upstream to the gene's coding region.

All other options are incorrect:

b). start codon, d). 3` UTR and e). stop codon are located downstream of the gene’s coding region.

c). origin of replication is not related to transcription it is the site where DNA replication begins.

Q. Transcription results in the production of (select all that apply):

Ans. The correct options are a). rRNA c).tRNA and d). mRNA.

Transcription is a process in which a given DNA sequence (gene) is transcribed into RNA sequence with the help of an enzyme RNA polymerase.

All other options are incorrect:

b). RNA polymerase is an enzyme that help in transcription.

e). polypeptides and f). enzymes are formed by translation.

g). DNA and h). Okazaki fragments are formed during replication.
