What happens during prophase quizlet?
What happens during prophase? A cells genetic DNA condenses, spindle fibers begin to form and the nuclear envelope dissolves.
How many replicated chromosomes are in prophase?
Sister chromatids. 4. In Model 1, how many replicated chromosomes does the cell contain during prophase? Four.
Do chromosomes replicate in prophase?
As the chromosomes condense they get shorter and thicker and can be seen through the microscope as individual structures (Fig. 3). The chromosomes at prophase will consist of two identical parts called sister chromatids that stay connected at the centromere. It is now clear that the chromosomes have been replicated.
