Which of the following RNAs is not required for the synthesis of protein?
1 siRNA
2 mRNA
3 tRNA
4 rRNA
Explanation:
siRNA (small interfering RNA) also known as silencing RNA. It is double stranded RNA molecules that inhibit the translation of specific mRNA. It is associated with pest resistance in plants by RNA interference.

What is the role of RNA polymerase III in the process of transcription in eukaryotes?
1 Transcribes only snRNAs
2 Transcribes rRNAs (28S, 18S and 5.8S)
3 Transcribes tRNA, 5s rRNA and snRNA
4 Transcribes precursor of mRNA
Explanation:
RNA polymerase III transcribes the genes for tRNAs and for the smallest species of ribosomal RNA (5S rRNA) RNA polymerase III is involved in transcribing tRNA, 5s rRNA and SnRNA.

Many ribosomes may associate with a single mRNA to form multiple copies of a polypeptide simultaneously. Such strings of ribosomes are termed as
1 Polysome
2 Polyhedral bodies
3 Nucleosome
4 Plastidome
Explanation:
Polyribosome (or polysome or ergosome) is a group of ribosome bound to an mRNA molecule like beads on a thread. Polyribosome which in group translating an mRNA sequence simultaneously. In prokaryotes, the polysomes may form while the mRNA is still being transcribe from the DNA template. Plastidome is the united form of plastid present in a Eukaryotic cell. Nucleosome is the basic structural unit of DNA packaging in Eukaryote. Polyhedral body are bacterial micro-compartments that contain enzymes involved in carbon fixation.

The back bone of RNA consists of which of the following sugar?
1 Deoxyribose
2 Ribose
3 Sucrose
4 Maltose
Explanation:
The back bone of RNA is the ribose sugar in its structure. RNA consists of a ribose sugar, which is a monosaccharide and is a carbon sugar, where as DNA consists of deoxyribose sugar which, via a glycosidic bond, is connected to a nitrogenous base at the first carbon.
