Q. A number of cell-cycle mutations including wee1ts have been isolated in the fission yeast S. pombe. Cells carrying wee1ts mutation grow generally at the permissive temperature. Though, at the restrictive temperature, the minimum size required to enter mitosis is decreased greatly; as a result, diminutive daughter cells are produced.
In subsequent cell cycles at the nonpermissive temperature, what are the expected duration of the cell cycle relative to normal as well as the expected relative duration of the G1 and G2 phases?
