The biosynthesis of ribosomal RNA occurs in:
1. Ribosomes
2. Golgi apparatus
3. Microbodies
4. Nucleolus
Statement I: | Larger and more numerous nucleoli are present in cells actively carrying out lipid synthesis. |
Statement II: | RER is frequently observed in the cells actively involved in protein synthesis and secretion. |
Non-membranous nucleoplasmic structures in the nucleus, are the sites for active synthesis of:
1. | protein | 2. | mRNA |
3. | rRNA | 4. | tRNA |
Statement I: | The content of nucleolus is continuous with the rest of the nucleoplasm as it is not a membrane bound structure. |
Statement II: | The outer nuclear membrane usually remains continuous with the endoplasmic reticulum but does not bear ribosomes on it. |
Statement I: | Mature sieve tube elements of vascular plants and mature human erythrocytes are not considered as ‘living’ cells. |
Statement II: | Mature sieve tube elements of vascular plants and mature human erythrocytes lack a nucleus. |
