Answer to: Describe what happens to the chromosomes in the following stage of Mitosis: Pro-metaphase. By signing up, you'll get thousands of...
Describe what happens to the chromosomes in the following stage of Mitosis: Prophase. Complete the following statement to describe nondisjunction and the resulting effects on chromosome number. During meiosis II, if the sister chromatids fail to separate and both daughter chromosomes go into the same...
When chromosomes replicate, or make copies of themselves in preparation for mitosis, the template chromosome remains joined to the new chromosome at a point called a centromere. The two identical joined chromosomes are called chromatids. Chromosomes are usually asymmetrical along their long axis, meani...

The organelles within a cell are known as the ''little organs'' that help with maintenance and thriving aspects of the cell. The organelles are very important when it comes to the cells making energy, getting rid of wastes, and storing our genetic structure....
line up at the metaphase plate, under tension from the mitotic spindle. The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase,the spindle has captured all the chromosomes and lined them up at the middle of the cell, ready to divide...
What happens during the s phase of interphase? Cells Life: A cell has a life that is similar to most of the living organisms on Earth. They are born, they grow, and they reproduce by splitting into two new cells. Cells spend most of their life in a stage known as Interphase. ...
It can also dictate tissue architecture, as it does in many epithelia. One way to ensure the correct angle of cell division is through controlled orientation of the spindle at metaphase. What happens when that control is lost? Ongoing work suggests that the consequence of metaphase spindle ...
Without the kinetochore, chromosomes wouldn't align at the metaphase plate. 4 Centromere The centromere is the specialized DNA sequence of a chromosome that links a pair of sister chromatids (a dyad). During mitosis, spindle fibers attach to the centromere via the kinetochore. Kinetochore A kinet...
The events that occur in meiosis but not mitosis includehomologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads. Why is meiosis 2 necessary? The two chromosomes are not seperated during Meiosis I. The cells are diploid, thereforein order to distribute...
