Answer: Unlike mitotic cells, meiotic cells undergo two divisions to produce haploid cells, allowing for genetic diversity in sexually reproducing organisms.
Explanation:
Both meiosis and mitosis are types of cell division. However, unlike mitosis that occur at one division only and yield two daughter cells with diploid number; meiosis involves two division steps:
- Meiosis I
where the parent cell is halved in chromosome number, and genetic materials are mixed between chromatids
-Meiosis II
where the two daughter cells generated in meiosis I is further divided into four haploid cells.
Answer:
This
Explanation:
In dehydration synthesis reactions, a water molecule is formed as a result of generating a covalent bond between two monomeric components in a larger polymer. In hydrolysis reactions, a water molecule is consumed as a result of breaking the covalent bond holding together two components of a polymer.Aug 14, 2020
Words can only describe but if you have a model you can show people what is happening rather them just using their imagination
Answer:
Option 3, Chromatids remain attached to one another until anaphase
Explanation:
Centromere lies at the center, end or other points of the chromosome and joins the two sister chromatids. During cell division, the spindle fibers attaches at the centromere and detaches the chromosomes during the anaphase of the cell division to ensure that each daughter cell gets equal number of chromosomes at the end of mitosis. Centromere plays an essential role in the separation of chromosomes.
Hence, option 3 is correct
