Deoxyribonucleic acid (DNA) is the hereditary material that lies within the nucleus of all cells in humans and other living organisms. Most of the DNA is placed within the nucleus and is called nuclear DNA.
A chromosome is made up of two chromatids which are joined by the centromere. The chromatids separate from each other during mitosis to form two new chromosomes. The DNA making up a chromosome is dispersed as chromatin.
Under a microscope, chromatids look like little dots and chromosomes are lines.
Answer:
The nucleus is dissolved during prophase II. In metaphase II the chromosomes line up single file down the metaphase plate of the cell. In anaphase II, the sister chromatids split up.
Explanation:
After meiosis I, meiosis II happens, which is like mitosis in the fact that sister chromatids are separated and migrate towards different daughter cells, resulting in four daughter cells with an haploid number of chromosomes.
