How are viruses used in gene therapy?

1 answer:

6 0

Answer: B. certain viruses are used as vectors because they can deliver the new gene by infecting the cell. the viruses are modified so they can't cause diseases when used in people.

During the early days of deciphering the human genome, scientists were surprised to find that the number of genes appeared to be

Alekssandra [29.7K]

Given what we know, we can confirm that the aspect of nucleic acids and transcription that can help explain this discrepancy is that of alternative splicing.

<h3>Alternative Splicing.</h3>

This process allowed the cells to use a single gene for the creation of various proteins.
This process includes the separation of RNA at splicing sites to create new versions of the mRNA strand.
This helps to increase the diversity of mRNA's available and create more proteins.

Therefore, given that alternative splicing allows the cells to create multiple forms of distinct proteins from a single gene, this allowed our organisms to develop the vast number of proteins we use, without the need for a much larger genome.

b. In 1979, the estimated elephant population was 1.3 million and in 2007 it was 640,000. By approximately what percentage did t

saveliy_v [14]

Answer:

The initial amount, 1.3 million = 1,300,000 is the 100%.

now, 640,000 is a given percentage (lower than 100%) of that.

How we can find it?

suppose that 640,000 represents an x%.

Then we have that the quotient between the actual quantities and the percentages must be the same

(640,000/1,300,000) = x%/100%

x% = (640,000/1,300,000)*100% = 49.23%

Then the percentage declined is:

100% - 49.23% = 50.77%

The other question can not be answered with the given information.

olchik [2.2K]

Answer:

Domains

Explanation:

All Biological organism can be classified or placed in a group.

Taxonomy is a branch of science that deals with naming and classification of biological organism based on shared characteristics.

In taxonomy, a domain is the highest order of classification or ranking ,its even higher than the kingdoms.

It is inclusive of all biological grouping.

All cellular organisms can be placed in any of the three domains namely, Bacteria, Archaea and the Eukarya.
