Question

Separating of chromatids during metaphase and behaviour of chromosomes during mitotic and meiotic divisions can be best studied by

• A. Phase contrast microscope
• B. SEM
• C. X-ray microscope
• D. Cell fractionation method

Answer 1

The correct option is A Phase contrast microscope

The stages of mitosis and meiosis were originally detailed after careful analysis of fixed cells. More recently, time lapse photography coupled with phase contrast microscopy has allowed to visualize the process entirely. This is because, the cellular movements of the live cells can be observed by phase contrast microscope.
