What is the common point of similarity between DNA and RNA?
1 Both are double stranded
2 Both have identical sugar molecules
3 Both have identical pyrimidine bases
4 Both are polymers of nucleotides
Explanation:
DNA and RNA both are polymers of nucleotides. DNA is act as a hereditary material which helps in transfer of character from one generation to another while RNA helps in synthesis of protein an act as catalyst. DNA \(\xrightarrow{\text { transcription }}\) RNA \(\xrightarrow{\text { transcription }}\) Protein

Ribosomal RNA is actively synthesized in:
1 Nucleoplasm
2 Ribosomes
3 Lysosomes
4 Nucleolus
Explanation:
Nucleolus is the centre for synthesis of ribosomal RNA (rRNA) that form ribosomal subunit. Ribosomal proteins migrate to the nucleolus from their assembly sites in the cytoplasm and surrounded by ribonucleoproteins. - These returns to the cytoplasm where they become mature ribosome particles.

Which one of the following also acts as a catalyst in a bacterial cell ?
1 23 S RNA
2 5 S RNA
3 Sn RNA
4 hn RNA
Explanation:
23S RNA \(\rightarrow\) It is a part of larger subunit at the ribosome in bacteria and act like as an enzyme known as ribozyme. It helps in peptide bond formation and also act as a catalyst in bacterial cell. - Sn RNA \(\rightarrow\) Sn RNA don't play any role as a catalyst. - hn RNA \(\rightarrow\) hn RNA is heterogenous nuclear RNA which is formed before formation of mRNA.

RNA is not found in
1 Chromosome
2 plasmalemma
3 nucleolus
4 ribosome
Explanation:
Plasmalemma is a less common term for the cell membrane. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell. It is a semipermeable membrane that encloses the cell's cytoplasm and nucleoplasm and separates the cell from the extracellular fluid.

The biosynthesis of ribosomal RNA occurs in:
1 Nucleolus
2 Ribosomes
3 Ribosomes
4 Microbodies
Explanation:
The biosynthesis of ribosomal RNA occurs in nucleolus. The nucleolus is a specialized sub compartment within the nucleus of a eukaryotic ell, responsible for the production and assembly of ribosome's. Ribosomes are composed of rRNA and proteins.
