Individuals with a mutation in the gene for apolipoprotein B-100 produce very low levels of this protein, which is a component of LDL. How would accumulation of fat in the liver be affected and would this result in hypercholesterolemia or hypercholesterolemia

Answers

Answer:

Fats would accumulate in the liver and the individual would show hypocholesterolemia

Explanation:

Familial hypercholesterolemia is a genetic disorder caused by a reduction and/or defect in the low-density lipoprotein (LDL) receptor. Moreover, apolipoprotein B is the unique protein component of LDL, which plays a critical role in lipid metabolism by binding the LDL receptor. Familial defective apolipoprotein B-100 refers to an inherited disorder associated with mutations of the apolipoprotein B-100 that leads to moderate or severe cases of hypercholesterolemia. Mutations in apolipoprotein B-100 are associated with a reduction in the binding capacity of LDL to the LDL receptor, thereby leading to hypercholesterolemia.

If new genetic variation in the experimental populations arose solely by spontaneous mutations, then the most effective process for subsequently increasing the prevalence of the beneficial mutations in the population over the course of generations is

Answers

Answer:

binary fission

Explanation:

Binary fission is the main type of reproduction of prokaryotic organisms. In binary fission, the prokaryotic cell first duplicates its DNA and then divides into two cells, each one receiving one complete DNA molecule. Since binary fission is a type of asexual reproduction, this process increases the prevalence of beneficial mutations in a bacterial population. Moreover, transduction refers to the process by which a virus transfers genetic information from one bacterium to another bacterium. Conjugation is also a sexual mode of transfer of DNA from a donor (F+) to a recipient (F−) bacterial cell by direct cell-to-cell contact. Finally, transformation refers to the transfer of genetic material by which bacteria take up exogenous DNA from the environment and integrate it in their genomes.

Why making anti-viral medicines is harder than making anti-bacterial medicines ?

Also Is Virus a living parasites?​

Answers

Answer:

Making anti-viral drugs is more difficult than making anti-bacterial medicines because viruses have very few biochemical mechanisms of their own. They make use of host machinery which replicates. So it is very much difficult to find the targets where these drugs get interfered by not making any harm to the host. Thus, it is not easy to design an antiviral drug with high safety and effectiveness.

Explanation:

And i would say virus is a parasites but not a living parasite according to md

Answer:

Because antivirals can damage host cells where the viruses reside.

I hope this helps

all viruses are obligate parasites,that is they lack metabolic machinery of their own to generate energy or to synthesize proteins,so they depend on host cells to carry out these vital functions...

There is a famous psychology experiment where people sit in classroom in such a way that the person on either side of you can't hear what you say. This works best with more than 20 people.

The first person composes a sentence that has 3 facts in it. He whispers it to the second person who relays it to the third until the last person is told. The point of the experiment is to show that the last person isn't normally able to correctly repeat the 3 facts. In fact, most often what is given is quite mixed up and incorrect.

That's what's wrong with eye witness accounts. You can be certain of what you saw. You can also get it all mixed up.

Abraham Lincoln grew up in a log cabin in Kentucky. He worked as a shopkeeperand a lawyer before entering politics in the 1840s. Alarmed by his anti-slavery stance, the southern states seceded soon after he was elected president in1860. Lincoln declared that he would do everything necessary to keep the United States united as one country. He refused to recognize the southern states as an independent nation and the Civil War erupted in the spring of 1861. On January 1,1863, Lincoln issued the Emancipation Proclamation, which freed the slaves in the southern states and laid the groundwork for slaves to eventually be freed across the country. He narrowly won re-election in 1864 against opponents who wanted to sign a peace treaty with the southern states. On April 14, 1865, Lincoln was assassinated by John Wilkes Booth, a southern sympathizer. All of the following statements are true, except for which?A. LIZMB. FG = JKC. ZJE ZFD.
