<span>Well this isn't actually a question but to market to a company like this you first have to impress a small number of people in a single chain of command. Your products don't have to be marketed to a company as a whole or to a single rung of the food chain but to each successive member in a hierarchy in the company. Firstly to the employee, then to their management then to the ones who actually making the decision to buy.</span>

Anton [14]

Answer:

(A) two

Explanation:

A heterodimeric protein consists of two polypeptides (a polypeptide is a  chain of amino acids) that differ in amino acid composition, number or order in the chain sequence. Each polypeptide makes a different subunit of the protein.

One gene encodes one polypeptide, so if the protein has two different polypeptides, two genes are required to form this protein.

gtnhenbr [62]

Answer:

With respect to the cases of early-onset Alzheimer’s disease are inherited, a type known as familiar Alzheimer’s disease (FAD), the statement is best supported by this information is that FAD is the result of a genetic change in one or more chromosomes.

Explanation:

Options for this question:

  • <em>FAD is the result of a genetic change in one or more chromosomes.</em>
  • <em>Natural selection will continue to reduce the incidence of FAD.</em>
  • <em>FAD affects only the genes of middle-aged people.</em>
  • <em>Deletion of one amino acid causes FAD.</em>

Alzhaimer's disease is a type of dementia that is characterized by neuronal degeneration, causing disorientation, memory and manual skills loss , among others. The familiar variety (FAD) is hereditary and is associated as a cause of disease and early Alzhaimer, before 60-65 years.

So far, three types of mutated genes related to FAD have been established:

  • PSEN₁ or presenilin-1 gene , more frecuent.
  • APP or amyloid precursor protein gene.
  • PSEN₂ or gene for presenilin-2, very rare or uncommon.

In some cases, people affected by FAD have alteration in more than one gene at the same time.

For this reason, it can be stated that FAD is the result of a genetic change in one or more genes or chromosomes.
