Question

what is proved by postural and Johnson from cell fusion technique​

Answer 1

Answer:

Cell fusion experiments conducted by Potu Rao and Robert Johnson demonstrated the dependence of the S phase on M phase. They isolated and fused cells in different phases of the cell cycle to form hybrids. When cells in S/G1/G2 are fused with a mitotic cell, the non-mitotic nucleus is driven into mitosis.
