Match List I (Sub-structures) with List II (Functions) and select the CORRECT answer using the codes given below the lists:
| List-I (Sub-structures) | List-II (Functions) | ||
| (A) | Nucleosome | (1) | Cementing to keep neighbouring cells together |
| (B) | Tubulin | (2) | A storehouse of oils and lipids |
| (C) | Adhering junctions | (3) | Structural units of chromatin |
| (D) | Elaioplasts | (4) | Protein units of microtubules |
| (5) | Oxidative phosphorylation |
Options:
Answer:
B
Solution:
DNA is wrapped histone proteins to form beads like structure called nucleosomes. This structure is further condensed to fit in a coiled helical structure called solenoid that on folding forms the chromatin fibre. Nucleosome forms the structural unit of chromatin fibre.
Microtubules found in the cytoplasm of eukaryotic cells are made of polymers of protein, tubulin. Microtubules help with the structure and shape of the cell.
Tight junctions are a type of cell junctions found in epithelial tissue that help to stop substances from leaking across a tissue.
Elaioplasts are a type of leucoplast store oils and fats.
