Answer:

regulating the transport of mRNA to the cytoplasm

Explanation:

In eukaryotes, the process of transcription occurs in the nucleus while ribosomes are present in the cytoplasm or on the surface of the rough endoplasmic reticulum. Therefore, the mRNA should leave the nucleus and enter the cytoplasm to serve in the process of protein synthesis. The nuclear envelope contains the nuclear pore complex (NPC). The nuclear pore complex includes several specific nucleoporins embedded in the nuclear envelope.

The NPC serves as the passageway for the transport of mRNA molecules to the cytoplasm. The mature mRNA binds to specific exporter proteins in the nucleus and forms ribonucleoprotein particles that are allowed to pass through the nuclear pore complex.

The middle and carboxyl domain of mRNA exporter binds to the phenylalanine-glycine (FG) repeats in FG nucleoporins to facilitate the mRNA transport. Therefore, the transport of mRNA from the nucleus to the cytoplasm is regulated by the nuclear pore complex. This is how the nuclear membrane is involved in the regulation of gene expression.

Nataly [62]

Answer:

See below

Explanation:

Marie Curie died of aplastic anemia in 1934. Aplastic anemia is an autoimmune disease in which the body fails to produce blood cells in sufficient numbers. Blood cells are produced in the bone marrow by stem cells that reside there. Aplastic anaemia causes a deficiency of all blood cell types: red blood cells, white blood cells, and platelets.

Fatigue is a symptom of aplastic anemia as the blood doesn't have the necesarry red blood cells to transport the oxygen to the organs.

Rapid heart rate happens because the body senses the decrease of oxygen's concentration and the hearts beats faster to provide the organs of oxygen.

Pale skin happens because the blood vessels are contracted in order to provide oxygen to the important organs of the body as the brain and heart. It means that less blood reaches the face and it shows as pale skin.

Prolonged bleeding from cuts happens because there aren't enough platalets to produce a blood clot to stop the bleeding.

Dizziness happens because there is not enough oxygen arriving to the brain.

If she is A negative, she can only receive blood from others A negative donors, or O- donors. This is because she has antibodies to B, and to groups that have the protein Rh (+). So she can't receive blood either B nor Rh+.

Enolase is an enzyme that catalyzes one reaction in glycolysis in all organisms that carry out this process. The amino acid sequ
Tom [10]

Answer:

Enzymes are influenced by changes in pH. Enzymes are best dynamic at ideal pH. It is the most favorable pH value - where the compound is most dynamic. Above and beneath to this ideal pH influence enzyme action. Accordingly enzyme show catalytic action at ideal pH.  

At the point when enzymes are st low or high pH. Hydrogen particles interface with amino corrosive present at dynamic site. In this way changes their state of amino acids, their legitimate direction and influence enzyme movement.  

While estimating action of enolase . 2 phospho glyceraldehyde is a substrate for enolase included a response tube. After appropriate in hatching measure of item is estimated (PEP). Proportion of PEP to 2 phospho glyceraldehyde gives thought regarding enzyme action.  

For negative control, we will take a response tube, without having any enzyme enolase in it. Along these lines we will ready to preclude any change of 2 phospho glyceraldehyde to PEP without enzyme.  

All compound present in our body are adjusted to as per the earth where we are living. In this manner makes us effective in C. aurantiacus ideal temperature for enolase is 55 degrees. So this catalyst will consistently work best at 55 degrees than at 37 degree .

malfutka [58]

Answer:

This is an illustration of epistasis type of gene interaction.

Explanation:

On crossing AaBb * AaBb, the offspring produced are mentioned in the Punnett square given in the attachment below. Based on the Punnett square, the phenotypic ratio will be 9 (orange): 4 (cream) : 3 (yellow).  

The given case is an illustration of the epistasis kind of gene interaction. When two or more distinct gene loci take part in the formation of similar phenotype, however, not additively is termed as epistasis, that is, it is the non-allelic association between the alleles situated at a distinct gene locus. In the phenomenon of epistasis, one of the gene loci modifies or masks the phenotype of a second gene locus.

Veseljchak [2.6K]
During winter time, the decreased total number of sunlight would affect the process of photosynthesis. Sunlight is one of the most essential ingredients in photosynthesis and without it, it wouldn't be possible. Therefore, the effect of this would be, the process of photosynthesis would be slowed down.
