During which phase do the chromosomes start to condense quizlet?
In late prophase (sometimes also called prometaphase), the mitotic spindle begins to capture and organize the chromosomes. The chromosomes finish condensing, so they are very compact. The nuclear envelope breaks down, releasing the chromosomes.
What happens in G2 phase?
During the G2 phase, extra protein is often synthesized, and the organelles multiply until there are enough for two cells. Other cell materials such as lipids for the membrane may also be produced. With all this activity, the cell often grows substantially during G2.
What happens in anaphase of mitosis?
During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle. … The separated chromosomes are then pulled by the spindle to opposite poles of the cell.
What is metaphase in mitosis?
Metaphase is the third phase of mitosis, the process that separates duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. … There is an important checkpoint in the middle of mitosis, called the metaphase checkpoint, during which the cell ensures that it is ready to divide.
In which phase of mitosis do chromosomes condense quizlet?
In prophase stage of mitosis, the chromosomes start to condense and become visible as two chromatids, joined by a centromere.
What happens during anaphase B?
Anaphase B spindle elongation is characterized by the sliding apart of overlapping antiparallel interpolar (ip) microtubules (MTs) as the two opposite spindle poles separate, pulling along disjoined sister chromatids, thereby contributing to chromosome segregation and the propagation of all cellular life.
Which occurs in anaphase quizlet?
What happens during Anaphase? The spindle fibers SPLIT APART the sister chromatids and move them to opposite ends of the cell, equally dividing the genetic material.
