Q. Consider the following statements:
1.In transcription, the transfer of genetic instructions in DNA to mRNA takes place in the nucleus.
2.The process of translation occurs at the ribosome located inside nucleus.
3.The transcriptome is the full range of messenger RNA (mRNA) molecules expressed by an organism.
Which of the statements given above are correct?

[A] 1 and 2 only

[B] 2 and 3 only

[C] 1 and 3 only

[D] 1, 2 and 3

Answer: C

Notes:

Explanation: Statements 1 and 3 are correct

Statement 1 is correct: Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus.

Statement 2 is incorrect: Translation occurs at the ribosome in cytoplasm, which consists of rRNA and proteins.

Statement 3 is correct: Transcriptome: The term “transcriptome” can also be used to describe the array of mRNA transcripts produced in a particular cell or tissue type. So a transcriptome is the full range of messenger RNA, or mRNA, molecules expressed by an organism.
