Prophase is the first phase of mitosis. During this phase, the chromosomes inside the cell's nucleus condense and form tight structures. In fact, the chromosomes become so dense that they appear as curvy, dark lines when viewed under a microscope. Because each chromosome was duplicated during S phase, it now consists of two identical copies called sister chromatids that are attached at a common center point called the centromere.
At the start of metaphase, the microtubules arrange the chromosomes in a line along the equator of the cell, known as the metaphase plate . The centrosomes, on opposite poles of the cell, then prepare to separate the sister chromatids.
After metaphase is complete, the cell enters anaphase. During anaphase, the microtubules attached to the kinetochores contract, which pulls the sister chromatids apart and toward opposite poles of the cell . At this point, each chromatid is considered a separate chromosome.
Finally, once anaphase is complete, the cell enters the last stage of the division process — telophase. During telophase, the newly separated chromosomes reach the mitotic spindle and a nuclear membrane forms around each set of chromosomes, thus creating two separate nuclei inside the same cell
During cytokinesis the cytoplasm then divides to produce two identical cells.
Answer:
Gluconeogenesis is needed to increase the blood glucose level and glycolysis is need to decrease or to move down the blood glucose level
Explanation:
Gluconeogenesis and glycolysis occur inside our body in response the blood glucose level.
When blood glucose level is low at that time gluconeogenesis is triggered by hormone glucagon released from alpha cells of pancreas by the same way when the glucose level is high at that time glycolysis is triggered by the insulin hormone.
The two processes gluconeogenesis and glycolysis occur in oue body to maintain homeostasis of blood glucose level.
Proteins are modified within the nucols
Answer:
Viruses may be defined as the organisms that shows the border line between the living and non living organisms. Viruses can only replicate when they enter in the body of a particular host.
Viruses are pathogenic for humans and can cause deadly diseases like AIDS. The pandemic condition of virus mainly depends on the the matter of time. The appearance of the disease condition before the occurrence of the another disease.
A protist has a nucleus inside of it to make it a Eukaryote, if it had no nucleus it would be consider a Prokaryote
