The potential outcome of a mutated MAD protein is development of aneuploidy in daughter cell.

Further Explanation:

The cell cycle is referred as the prearranged flow of steps that include the cellular division as well as cell growth. This cycle form two new daughter cells. The cycle is begins with the interphase. In this phase, mainly the cell replicates and matures its DNA.

The second stage of a cell cycle is the mitosis or M phase. Mitosis is a kind of cell division. In this, parental cells divide into two daughter cells which have the same number of chromosomes as that of the parent cell

MAD protein is a kind of a protein that mainly present in humans and this protein is encoded by MXD1 gene. This protein is mutant cell that is referred as mitotic arrest deficient. This protein has a role in recruiting an inhibitor MAD-2 which is anaphase inhibiter help in dissociating the kinetochores.

Development of any Mutations in the MAD protein can develop a defective protein and malfunction of the checkpoints. The cell ends the cell cycle by the last stage which mitosis. In the presence of mutated MAD protein daughter cell cannot develop properly. Daughter cell can have very low or high number of chromosome and can result in aneuploidy condition. Mainly aneuploidy cell develop or result in cancer cell.

MAD protein are mutants cells and they can be refers to as mitotic arrest deficient. MAD protein act by recruiting the anaphase inhibitor MAD2 to dissociate kinetochores and its essentials from MAD2-CDC20 complex formation in vivo.

However, there mutation will produce defective protein and checkpoint failure by resulting into aneuploidy. Aneuploidy is when a cell finishes the process of mitosis and produces daughter cells with few or too many chromosomes and aneuploidy causes more than 90% of human cancer.

Will fossil fuels ever run out

Anni [7]

Well fossil fuels are a finite resource and at the rate we are using them, yes they will run out. but not anytime soon. but yes. we use them faster than they can be created. they WILL run out eventually.

What components of the eukaryotic cell were visible in the onion root tip? Which components were not? Why do you think some comp

ruslelena [56]

Looking at the onion root tip under the microscope you can see large, rectangular cells with visible distinct cell walls surrounding it (cells have a more regular shape because of the wall). Inside the cells, you can notice darkly stained nucleus, large vacuoles at the center and sometimes small granules within the cytoplasm. Looking the onion root tip under the microscope is often the way to observe mitosis. Usually, you cannot see organelles such as mitochondria, ribosomes, rough and smooth endoplasmic reticulum, centrioles and Golgi body as they appear translucent and because are too small to be seen under the light microscope (electron microscope required). Also, chloroplasts are not present in an onion cell because it is not a photosynthetic cell.

Testing Two-Point Discrimination

yanalaym [24]

Two-point discrimination is the minimal distance which someone can perceive two different stimuli that given simultaneously. An area with higher receptor density will have a lower two-point discrimination result since the distance between receptor is lower.
The area that needs a high sensitivity like the palm of the hands(especially the fingertips), face, and tongue should be the one with lowest two-point discrimination.

In this report, anterior forearm two-point discrimination result is the lower than the fingertip. This result is suspicious since the forearm shouldn't more sensitive than the fingertip. Fingertip two-point discrimination is around 2-6mm and forearm should be much higher than 6mm.

What do you think the odds were that two children would turn out exactly alike

Anna007 [38]

No 2 people in the world are "exactly alike", so the odds would be 0% chance. Twins, might be closer in alike-ness, but they still aren't "exactly alike". Hope this answered your question.

finlep [7]

Answer:

GG, Gg, Gg, gg

Homozygous green – GG

Heterozygous green – Gg

Homozygous yellow - gg

Explanation:

It is given that allele for green seed pods (G) is dominant to the allele for yellow seed pods (g) which means that if “G” and “g” occur together, a trait associated with G will be expressed.

The genotype of the true breeding Green plant is “GG”

The genotype of the true-breeding yellow plant is “gg”

F1 generation cross

GG * gg

Offspring produced from F1 generation are – Gg, Gg, Gg, Gg

In f2 generation offspring of F1 generation are crossed among each other.

So the offspring produced in F2 generation are

Gg * Gg

GG, Gg, Gg, gg

Homozygous green – GG

Heterozygous green – Gg

Homozygous yellow - gg
