The mitotic spindles arise from which cell structure?

Biology
1 answer:
Lapatulllka [165]3 years ago
5 0

Answer:

The correct option is : b. centrosome

Explanation:

Centrosome is a cell organelle, which acts as the microbule organizing center and also regulates the cell cycle progression in an eukaryotic cell.

During the prophase stage of the cell cycle, the centrosomes are associated with the membrane of the nucleus. The nuclear membrane ruptures during the mitosis and the interaction of the centrosome nucleated microtubules with the chromosomes leads to the formation of the mitotic spindle.

<u>Therefore, mitotic spindles arise from the centrosome.</u>

If a cell contains a set of duplicated chromosomes, does it contain any more genetic information than the cell before the chromo
zmey [24]

Answer:

No.

Explanation:

When the set of chromosomes are duplicated, it means the chromosomes will be double the number.

However the genetic information will not change. It will remain the same.

Duplication of chromosomes is usually occurs among the interphase stage of mitosis where chromosomes will duplicate to ensure the formation of two identical daughter cells.

In these cells there will be no addition or variation in genetic information.

What causes antibiotic resistance?
Rama09 [41]

Answer:

Antibiotic resistance occurs when bacteria change in response to the use of these medicines. Bacteria, not humans or animals, become antibiotic-resistant. These bacteria may infect humans and animals, and the infections they cause are harder to treat than those caused by non-resistant bacteria.
