David is developing a model of mitosis. He plans to represent a cell with a paper circle, and to represent 6 chromosomes with co
Paraphin [41]

The most useful representation of metaphase would be  6 toothpicks at one end of the circle, and 6 toothpicks at the opposite end of the circle.

<h3> What are cytokinesis and mitosis?</h3>

Mitosis is a cell division type that divides the parent cell and the genetic material into two alike daughter cells with the same chromosome numbers.

Cytokinesis is a process by which at the end of the telophase the cytoplasm of the cell starts dividing and results in the formation of the plate in plants and furrows in the animal, dividing the cell equally.

Thus, option "B" is correct.

A cell has 6 chromosomes. How many chromosomes will each daughter cell have if it undergoes mitosis
77julia77 [94]

Answer:

At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.

hope this helps

have a good day :)

If the DNA sequence TTCACG is transcribed to AAGGC, what type of mutation has occurred?
SashulF [63]
Insertion

Genetic stability maintenance  requires an extremely accurate mechanism for DNA replication and mechanisms for fixing the several accidental lesions that occur continually in DNA.  Spontaneous changes in DNA are temporary due to immediate correction process called DNA repair. DNA repair’s importance is very evident from the huge investment that cells form in DNA repair enzymes. In 1000 accidental base changes in DNA , fewer than one results in a permanent mutation due to the efficient elimination by the DNA repair.<span> </span>
