Which of the following is not a functional RNA?

Which of the following is not a functional RNA?

tRNA
rRNA
mRNA
snRNA
catalytic RNA

Which of the following is not required in transcription?

Template DNA strand
RNA primer
RNA polymerase
ATP
GTP

Expert Solution

A. The correct option is C) mRNA.

The functional RNA is the RNA that is non-coding RNA. This type of RNA cannot be translated. Here from the options, tRNA, rRNA, snRNA and catalytic RNA are functional RNAs. They do not code for a protein. They are involved in biological functions only.

mRNA is a coding RNA. They are involved in translation and they code for proteins.

A. The correct option is B) RNA primer.

The template strand is used by RNA polymerase to attach complementary bases during transcription.

ATP activates transcription initiation from promoters by RNA polymerase II.

Guanosine-5'-triphosphate (GTP) is one of the building blocks needed for the synthesis of RNA during transcription.

But RNA primer is nor needed in transcription.

Which of the following is this? a. 5' to 3' direction of synthesis b. RNA polymerase can begin synthesis of a new RNA strand by first adding nucleoside triphosphate; DNA polymerase requires a primer sequence c. New strands are produced by using existing strands as a template d. Synthesis requires nucleoside triphosphates as a cellular supply

One underlying theme of gene expression is that RNA often has a functional role beyond just transmitting sequence information from DNA to proteins. Describe one example (other than an mRNA) where RNA is doing something important for gene expression. Your answer should indicate the functional significance of the RNA and provide mechanistic insight.
