The virus that causes mumps in humans is composed of a protein outer shell containing a core of DNA. The virus that causes the f

lu in humans is composed of a protein outer shell containing a core of RNA. Vaccines that are effective against mumps work efficiently year after year. Vaccines that work against the flu must be revised and changed every year. What accounts for the difference in the effectiveness of these two vaccines?

Flu vaccines need to be revised and changed every year because the flu virus constantly mutates. Flu viruses can change in two ways: drift or shift. Antigenic drift occurs when genes of the virus slowly change during replication until the immune system no longer recognizes it. On the other hand, antigenic shift occurs when a major change in the virus happens. This usually leads to a totally different kind of virus. This is what happened during the H1N1 scare in 2009.

DNA viruses like mumps are less prone to mutation due to the presence of DNA polymerase. RNA viruses are more prone to mutation because they undergo reverse transcription to simulate the role of DNA.

<h3>Amino acid</h3>

Amino acid can simply be defined as those organic molecules or substances which combine to form proteins. However, amino acids are generally characterized by some key features or properties; some of these properties of amino acids includes the following:

  • They are soluble in water
  • They are base units of proteins
  • Amino acid are insoluble in organic solvent
  • Amino acids are colourless
  • They are crystalline solid
  • All amino acids however too, have at least one acidic carboxylic acid (-COOH) group and one basic amino (-NH2) group.

So therefore, the correct answer choice among the statement above about strings of amino acids which can be decoded using single letter amino acid abbreviations to a type of

secondary structure is:

Alanine luecine proline histidine alanine histidine glutamic acid leucine isoleucine cysteine glutamic acid serine. Option a is the correct answer

in a population of sexually reproducing bacteria how can we select for the resistant ones by only taking antibiotics for 2 days
VladimirAG [237]

We can select the resistant microbes that were survived on the second day of antibiotic application.

<h3>How can we select for the resistant ones?</h3>

We can select for the resistant ones by only taking antibiotics for 2 days instead of the full 10 days that the drugs were prescribed in order to see the microorganism that survived on the second day. Bacteria get resistance when they are exposed to similar type of chemicals for a long time. Some of bacteria mutate and make defenses against the chemical which leads to survival of that organism.

So we can conclude that We can select the resistant microbes that were survived on the second day of antibiotic application.
