Question

If a hypothetical drug prevents actin from working properly, how would cell division be affected? DNA synthesis would not occur cell elongation during anaphase would not occur spindle formation would not occur spindle attachment to kinetochores would not occur cleavage furrow formation and cytokinesis would not occur

Answer 1

2nd option

First option is incorrect because DNA synthesis has nothing to do with the cytoskeletal elements.

Second option is correct because actin fibres are responsible for the elongation of cells during anaphase.

Third and forth options are incorrect because spindle formation and attachment is the function of microtubules and not actin.

Last option is incorrect because cleavage furrow formation and cytokinesis occur with the help of contractile ring.
