Would a cell with a homozygous, deleterious mutation in dynein routinely segregate sister
chromatids between daughter cells? Explain.
Homework Answers
Answer
A homozygous mutation in dynein will slow down the movement of chromosomes and diminished the orientation of chromosome but will not halt segregation of sister chromatid. Another player i.e. kinesis motor also involved in the process so double mutation of both the dynein and kinesin will completely halt the chromosome segregation between daughter cells.
