Site of formation of ribosomal precursor or ribosomal subunits in cell is
1 nucleus
2 nucleolus
3 nucleus body
4 stroma
Explanation:
Exp:B Nucleolus is spherical structure found in cells nucleus. Its primary function is to produce and assemble cells ribosome. It is the site of ribosomal RNA genes. Its main function is synthesis of RNA ribosome biogenesis. But exact mechanism of biogenesis of 70S type of ribosomes is less know. Perhaps the cell membrane and genophore play importance role in biogenesis.

A non-proteinaceous enzyme is
1 Iysozyme
2 ribozyme
3 ligase
4 deoxyribonuclease
Explanation:
Exp:B All enzyme are protein except ribozyme. Ribozyme is the only non proteinaceous enzyme, while lysozyme, deoxyribonuclease, ligase and all other enzymes are proteinaceous enzyme. - Ribozyme is a form of ribosomal RNA ( \(23 \mathrm{~S}\) r-RNA) which acts as a catalyst in splicing of RNA during protein synthesis.

DNA is not present in :-
1 Ribosomes
2 Nucleus
3 Mitochondria
4 Chloroplast
Explanation:
Exp:A Ribosomes do not contain DNA. It is organelles that are responsible for protein synthesis. DNA is mainly found in the nucleus, however, extra nuclear DNA is found in certain organelles. Mitochondrial DNA is significant in maternal Inheritance, where as chloroplast DNA consists of gene important for photosynthesis.

The solid linear cytoskeletal elements having a diameter of \(6 \mathrm{~nm}\) and made up of a single type of monomer are known as:
1 Microtubules
2 Microfilaments
3 Intermediate filaments
4 Lamins
Explanation:
Exp:B The solid linear cytoskeletal elements having a diameter of \(6 \mathrm{~nm}\) and made up of a single type of monomer are known as microfilaments. They are ultramicroscopic long, narrow, cylindrical rods or protein filaments which occur in eukaryotic plant and animal cells. Microfilament are made up of actin constituting 10-15\% of total cell protein. Cyclosis is caused by the activity of microfilaments.

Which one of the following structure is an organelle within an organelle?
1 Ribosome
2 Peroxysome
3 ER
4 Mesosome
Explanation:
Exp:A Ribosomes, are smalls dances rounded and granular partical of Ribonucleo protein. Ribosomes are found in matrix, cytoplasm and chloroplast and also attached with R.E.R and Nuclear membrane. Ribosomes are present in both prokaryotic and eukaryotic cell. In eukaryotic cells \(80 \mathrm{~S}\) ribosome (organelles) are attached to rough Endoplasmic Reticulum (ER) which is an organelle. It is also present in the organelles chloroplast (in plant cells) and mitochondria.
