Question

Which of the following statements concerning transcription is true?

Answer 1

Answer: Option A) All types of RNA in the cell are synthesized by transcription, which uses a portion of DNA as a template for copying.

Explanation:

All types of RNA:

- viral RNA,

- ribosomal RNA,

- transfer RNA,

- messenger RNA and

- double-stranded RNA, have a sequence that is the same as 'antisense' strand of the DNA.

Thus, it is true that all types of RNA in the cell are synthesized by transcription, which uses a portion of DNA as a template for copying.
