Answer:
Anaphase of meiosis II
Explanation:
I think you are asking during which phase of cell division sister chromatids are mostly likely to fail to separate properly, a phenomenon that can lead to genetic disease.
This is sometimes called non-disjunction, and it is most likely to occur in anaphase during meiosis II. During this stage, sister chromatids of the two daughter cells produced by meiosis 1 are separated and brought to opposite parts of the cell. If something goes wrong at this stage, the sister chromatids can fail to separate properly, meaning the daughter cells do not have the correct number of chromosomes (see attachment).
An example of such a genetic disorder is Down syndrome
The quinolone drugs are basically used for treating malaria. They inhibit the haem polymerization. after the breakdown of hemoglobin, the released haem rises to poisonous levels and leads to the death of the parasite, from its own toxic waste product.
During S phase stage of interphase the cells copy their chromosomes.
<u>Explanation:</u>
The S phase of a phone cycle happens during interphase, before mitosis or meiosis, and is liable for the amalgamation or replication of DNA. The cell makes an indistinguishable duplicate of every one of its chromosomes. Chromosomes are found inside the core of the cell and comprise of long strands of DNA that contain the hereditary data of the cell.
G2 stage: This happens after the DNA had been copied in S stage. At that point, at a basic point during interphase (called the S stage), the phone copies its chromosomes and guarantees its frameworks are prepared for cell division. The point of this procedure is to deliver twofold the measure of DNA, giving the premise to the chromosome sets of the daughter cells.
Answer:
One of the major goals of environmental science is to understand and to solve environmental problems. In order to accomplish this goal, scientists study two main types of interactions between humans and their environment. One area of focus is on how we use natural resources, such as water and plants.
Explanation:
Environmental science is important because it enables you to understand how these relationships work. For example, humans breathe out carbon dioxide, which plants need for photosynthesis. Plants, on the other hand, produce and release oxygen to the atmosphere, which humans need for respiration.
