A newly identified virus infects a eukaryotic host cell without producing virions right away, with a long period where the host is largely unaffected by the infection. What's the best description of this virus?
A: This virus rapidly causes lysis of the host cell
B: This virus has a long period of latency
C: This virus is a bacteriophage
D: This virus can't replicate

Answers

Answer 1

The best description of the virus is that the virus cannot replicate. The correct option is D.

What is a virus?

A virus is an infectious agent which is non-living normally, but it becomes alive when come in contact with any living cell. It causes many diseases in humans, animals, and plants.

Here, the virus is not producing virions, which means it doesn't cause lysis. It doesn't affect the host, so do not have a long period of latency, and is not a bacteriophage, so the virus is not replicating.

Thus, option D: This virus can't replicate is correct.

They look a little bit different. SA cells contain fewer mitochondria, fewer myofibers, and a smaller sarcoplasmic reticulum. This means that the SA node cells are less equipped to contract compared to the atrial and ventricular cells.

In quiet breathing, muscular effort is used mainly in inspiration, and expiration is largely passive, due to elastic recoil of the lung. It results in a pattern change between expiratory and inspiratory flow. Explain changes you observed in the recordings you obtained. 1 pts Enter your answer here

Answers

Answer:

During quiet breathing, the main muscular effort is made in the inhalation process and the expiration process is mainly passive as it depends on the inhalation.

The expiration occurs due to the elastic recoil that causes a decrease in volume. In this process, the contraction of the diaphragm helps in the inhalation which is least affected by the intercostal muscle. During quiet breathing, the rate of inhalation and expiration time is relatively proportionate to one another.

What is Breathing?

Breathing is the process of moving air into and from the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen.

Answer:

When recombination occurs during meiosis, the cell's homologous chromosomes line up extremely close to one another.

Explanation:

Writing Assignment So, you have learned about how the denaturation of proteins works during lecture, and you have seen examples in these videos. Now you will write a 2-3 page discussion of protein denaturation putting all that together Make sure you cover both the academic side (lecture knowledge) and practical side (what is done and observed in the lab). Make sure the answers to the following questions are contained in your report. Do NOT just answer them separately, but rather incorporate them seamlessly in your writing. This is a very broad topic, so comprehensive coverage is hardly expected, but you should demonstrate a good beginner's understanding. As usual, reference any and all resources you use.
a. What are the various levels of organization that any protein structure may have that gives it its 3-dimentional shape?Which of these changes during denaturation?
b. For each change made to a protein solution that you have seen or read about how might it affect the interactions that are involved in a protein's shape?
c. What is the difference between precipitation of a protein and its denaturation? How might you tell the difference?
d. If changing the pH of an enzyme solution greatly reduces the activity of that enzyme without precipitation, how could you tell in the lab if it were the result of denaturation or just going to a pH that is just not a good one for the enzyme? And how would a change in pH impact or even stop enzyme function without denaturation? (Consider the enzymes that are active in your stomach, such as pepsin-discussed in Wikipedia.)
e. For changes that precipitate a protein, are some more likely than others to be denaturation?
f. Etc. If you find one aspect of what you've see more interesting, go ahead and learn more and expand that section of your report and keep the other sections more basic.

Answers

Solution :

Denaturing may be defined as the process where the protein they lose their shape and their function because there is a change in the pH level or in the temperature. Although the amino acids sequence also known as primary structure, it does not change. But the shape of the protein might change a little bit so much that it can become dysfunctional in which protein is considered to be denatured.

The enzyme, Pepsin, the breakdown protein in our stomach only operates at a very low pH level. At higher pH level, the pepsin's configuration the way the polypeptide chain is being folded up in a 3 dimension begins to change. The pH level of the stomach is maintained at a low level to ensure that pepsin continues for the digest protein and that it does not denature.

There are 4 levels of the protein structure --- they are the primary, the secondary, the tertiary and the quaternary.

The primary protein is a particular sequence of amino acids in each of the polypeptide chain that makes the protein. The final protein structure depends on this sequence.

Secondary structure arise from the interactions between the neighboring or nearby the amino acids as polypeptide starts folding into 3D form.

The tertiary structure is the most important of structural levels in determining.

The quaternary structure also applies to the proteins made from more than one polypeptide chain.

To approximate the actual concentration of enzymes in a bacterial cell, assume that the cell contains equal concentrations of 1,000 different enzymes in solution in the cytosol and that each protein has a molecular weight of 100,000. Assume also that the bacterial cell is a cylinder (diameter 1.0 m, height 2.0 m), that the cytosol (specific gravity 1.20) is 20% soluble protein by weight, and that the soluble protein consists entirely of enzymes. Calculate the average molar concentration of each enzyme in this hypothetical cell.

Answers

Answer:

2.4 × 10⁻⁶ M

Explanation:

Molar concentration = no of moles of solute (enzymes)/volume of solvent(cystosol)

Let V = volume of solvent = volume of cystosol = πd²h/4 where d = diameter of cell = 1.0 m and h = height of cell = 2.0 m

Concentration of enzymes, C = n/V where n = no of moles of enzymes

Also, n = m/M where m = mass of all enzymes and M = molecular weight of protein = 100,000

Note that the solvent for the enzymes is cystosol, since they are dissolved in it.

Density of cystosol,ρ = specific gravity of cystosol in g/cm³ = 1.20 g/cm³.

Now, ρ = m'/V where m = mass of cystosol and V = volume of cystosol

m' = ρV

m' = 1.20V

Given that 20 % of the cystosol is protein and all protein are enzymes, the mass of enzymes is thus m = 0.2m' = 0.2 × 1.20V = 0.24V

C = n/V

= m/MV

= 0.24V/100000V

= 2.4 × 10⁻⁶ mol/cm³

= 2.4 × 10⁻³ mol/dm³

= 2.4 × 10⁻³ M

This is the concentration of all the 1000 enzymes.

So, the concentration of one enzyme is 2.4 × 10⁻³/1000 M = 2.4 × 10⁻⁶ M
