Which of the following cell type would be best choice for studying ? What is the most likely pathway taken by a newly protein that will be secreted by a cell? After DNA replication, each chromosomes has molecule(s) of DNA called , that after separation are known as chromosomes. The microtubules of the mitotic spindle attach to a specialized structure in the centromere region of each chromosome called the How does a nucleus in G2 phase of the cell cycle differ from a nucleus in G1 phase? A bacterial cell give rise to two genetically identical daughter cells process known asExplanation / Answer
64)The answer is 'C' that is phagocytic WBC. The lysosmes are present in the cytoplasm which contains digestive enzumes.These are called as suicidal bags of the cell as these helps in breaking down of cell components which are no more needed and helps in removal o bacteria that is engulfed by the cell.In the same manner the WBC acts as phagocytes by engulfing foreign particles that enters into the cell and fights against the infection.
65) The answer is 'D' that is ER--Golgi -- Vesicles that fuse with plasmamembrane. The pathway for synthesis of protein is originated in the rough ER and then it proceeds through the many compartments of the golgi apparatus and finally ends up in a vesicle that fuses with the cell plasmamembrane.
66) The answer is 'A' that is two, sister chromatids,daughter.After DNA replication each chromosome has two molecules of DNA which are called as sister chromatids and after their separation these are called as daughter chromosomes.
67)The answer is 'A' that is kinetochore. The microtubules of mitotic spindle fibres are attached to the specialyzed region in the centromere region of each chromosome is called as kinetochore.
68) The answer is 'A' that is the G2 phase has twice the amount of DNA as the G1 nucleus.
69) The answer is 'D' that is binary fission.
