Which type of gene therapy results in alteration of the DNA of a gamete or a fertilized ovum?
larisa86 [58]

Answer:

The correct option is: <u>e. Germline gene therapy</u>

Explanation:

The <u>germline gene therapy</u>, GGT is the <u>modification of the germ cells</u>. In this therapy, a functional gene is introduced into the genomes of the gametes. Such a modification of the germ cell results in all the cells of the organisms to get modified. This change can therefore be <u>passed on to the next generations.</u> Many countries such as Canada, Germany and Switzerland, have prohibited the use of the germline gene therapy on humans.

What are the reasons for the several day delay in a primary response. Infection______. A. transport to secondary lymphoid tissue
Liula [17]

Answer:

The correct answer is D. proliferation and differentiation.

Explanation:

Primary immune response occurs due to the first exposure of an antigen to the immune system. The primary immune response is generally delayed by many days because it takes time for B and T cells to become cloned and to proliferate and differentiate.

Then after several days of proliferation and differentiation of activated T and B cells, T cells become effector T cells and B cell becomes plasma cells which then eliminates the antigen. Memory B and T cells are also produced during this process which helps in generating a quick immune response during the second and subsequent exposure of that antigen.

So the correct answer is D. proliferation and differentiation.
