Question

a. S phase

b. G2 phase

c prophase

d. metaphase

e. anaphase

Answer 1

E Anaphase

Anaphase is preceded by metaphase, by the end of which fully condensed sister chromatids are arranged in pairs, their centromeres lying along a surface known as the metaphase plate. Spindle fibres (microtubules containing γ-tubulin) extend from the spindle poles to the centromeres . The point of contact is a protein complex called the kinetochore, and these fibres are sometimes referred to as spindle microtubules. Other spindle fibres do not contact the chromosomes but either connect directly with spindle fibres from the opposing pole (overlap microtubules) or with the cell cortex; these are astral microtubules.
