Describe the process of altering the genetic variation of a cell using a genetically modified virus for human gene therapy. In t
Len [333]
In human gene therapy, a genetically modified virus (a.k.a. a viral vector) can alter the genetic variation of a cell, but not all viral vectors do.

The process often begins with the delivery of or creation of a segment of viral double stranded DNA (containing the gene you want to introduce). Then typically an enzyme known as an integrase cuts the ends of the segment of viral DNA and also cuts open the cell's DNA. Then the viral DNA is integrated/ inserted into the cell's DNA. The connecting ends are ligated together and adjusted so that the nucleotide base pairs match up.

This in the future may affect the gene pool for instance if the viral DNA (your gene) was inserted in the middle of another gene or important regulatory sequence of the cell DNA, and this alteration may be passed on into offspring and become present in the gene pool, which could have bad effects.

The effects on the gene pool really depends on what the virus ends up doing. For example, it may fix the function of a damaged gene which is the goal, and allow for a working gene to be in the gene pool, which would be good. The problem with gene therapy is that it's difficult to predict 100% what the virus will do every time it is given to a patient.

But it's very important to consider that it will only affect the gene pool if the virus is able to enter and alter germ cells (reproductive cells). If the virus, enters somatic cells (regular body cells) this will not be passed on to future generations. So viruses can be designed to avoid germ cells and avoid this gene pool issue. Also, some viral vectors use viruses that do not integrate their DNA, the cells just express the viral DNA (create the desired protein from it) and over time the viral DNA is degraded/ lost which wouldn't pose this threat.

This is long, but I hope it helped!

Ecology is made up of _____. mathematics many sciences the science of biology animals
shtirl [24]

Ecology is made up of the science of biology. Ecology is a science that deals with the relationships between groups of living things and their environments. To exist with one another, organisms belonging to a same species either compete for the resources or divide it amongst themselves, where animals and plants of the same species co-exist and creates a beauty with nature.

sergejj [24]

Answer:

There is no short answer.

Explanation:

The primary difference between the periodic and perpetual inventory system is that the perpetual system keeps track of things from the start to finish continuously while the periodic system divides it into periods and keeps the records at the end of every set period of time.

How is RNA and DNA different
Shkiper50 [21]

-DNA is double stranded,RNA is one stranded

-DNA contains the following nitrogenous bases:Adeninde Guanine Timine Citozine while RNA contains Adeninde Guanine Citozine and Uracil

-DNA function is to contain the information for manufacturing proteins while there are many types of RNA with whole different jobs for example:messanger RNA(mRNA) it coppies a sequence from the DNA strand and takes it to the ribosome in order to be translated as the order for placing aminoacids in the polypeptide strand;transport RNA(tRNA) it is a short RNA strand containing up to 100 nucleotides it takes aminoacids to the ribosome so the polypeptides strand can start to be manufatured from aminoacids in an order inscripted in the mRNA.
