How many chromosomes are present in the daughter cells if a cell contains 16 chromosomes at the start of mitosis?
If a cell with 16 chromosomes undergoes mitosis, each daughter cell will also have 16 chromosomes.
How many chromosomes are present at anaphase If a cell contains 20 chromosomes at the start of mitosis?
If there are 20 centromeres seen in anaphase, then there are 20 chromosomes in the dividing cell. Thus each pole of the dividing cell will receive 10 chromatids: each chromatid will now become a chromosome for daughter cell.
What happens anaphase?
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.
How does anaphase I in meiosis differ from anaphase in mitosis?
In anaphase 1 in meiosis, homologous pairs are separated but sister chromatids stay joined together. In anaphase 1 of mitosis the sister chromatids do separate.
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.
Are there centromeres in anaphase?
During anaphase, paired centromeres in each distinct chromosome begin to move apart as daughter chromosomes are pulled centromere first toward opposite ends of the cell. During telophase, newly formed nuclei enclose separated daughter chromosomes.
Do centromeres exist in anaphase 1?
This creates two near-exact strands for each of the 46 chromosomes. To make sure they remain close to each other and do not cause genetic defects through ‘lost’ genetic material, these sister chromatids are joined by a centromere. Firstly, there is no anaphase I in mitosis, only anaphase.
Which process occurs during anaphase of mitosis quizlet?
Which of the following events occurs during anaphase of mitosis? The sister chromatids are pulled apart toward opposite sides of the cell.
