What problems could occur if the chromosomes has a very long thin shape during mitosis?

When cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other. This is called independent assortment.

What problems could occur during mitosis if the chromosomes had a long thin shape?

If they did not line up correctly, there would not be an equal amount of chromosomes in each daughter cell. There would either be too little or too many chromosomes in each cell, which could lead to non-functioning daughter cells.

What problems can occur during mitosis?

Mistakes during mitosis lead to the production of daughter cells with too many or too few chromosomes, a feature known as aneuploidy. Nearly all aneuploidies that arise due to mistakes in meiosis or during early embryonic development are lethal, with the notable exception of trisomy 21 in humans.

Why is it important for the chromosomes to condense during mitosis?

Chromosomes condense before mitosis to allow them the ability to move smoothly, without becoming entangled and breaking. (So, they are conveniently packaged for cell division, in which the chromosomes must move to both poles of the cell.)

When chromosomes appear as a long thin thread What are they called?

At the leptotene stage the chromosomes appear as long, thin threads.

How do cells grow and repair themselves?

As cells grow old, they wear off. Sometimes they suffer injury and bruises, but they are able to repair themselves by growing new cells in a process called Mitosis. As living things grow, they undergo a process called aging (age). Chromosomes make sure DNA is separated evenly during cell division.

What would happen if sister chromatids did not line up correctly?

If the sister chromatids did not line up at the equator, then there will not be an equal amount of chromosomes in each daughter cells. Colchicine is a poison that acts to inhibit the development of spindle fibers. … Only one of the DNA needs to be copied then they move to both sides of the cell and cytokinesis occurs.

What happens if mitosis does not occur?

If there is no mitosis, there would be no cell growth and cell reproduction. Most importantly, genetic information cannot be passed on. All cell functions would be hugely affected.

What are two reasons mitosis is important for organisms?

Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.

Why do chromosomes form during mitosis?

They form after DNA replicates and are the form in which the genetic material goes through cell division. Chromosomes contain genes, which code for proteins. Cell division in eukaryotic cells includes mitosis, in which the nucleus divides, and cytokinesis, in which the cytoplasm divides and daughter cells form.

What happens if chromosomes dont condense?

If they do not align correctly, they cannot move individually to opposite poles in the later phases of mitosis, and the result will be one cell with extra chromosomes and a daughter cell with missing chromosomes. These mutations can lead to harmful results such as cell death, organic disease or cancer.

Which of the phases of mitosis has the shortest duration?

In anaphase, the shortest stage of mitosis, the sister chromatids break apart, and the chromosomes begin moving to opposite ends of the cell. By the end of anaphase, the 2 halves of the cell have an equivalent collection of chromosomes.
