Answer:
--Block immune cells from crossing the blood brain barrier.
--Stimulate the regeneration of myelin.
Explanation:
Multiple sclerosis or shortly known as MS is an unpredictable disease caused in the humans. Multiple sclerosis affects the central nervous system of our brain which causes the disruption in the flow of the information within our brain, and between our brain and the body.
It is a very rare disease.
The symptoms of MS may vary and includes double vision, weakness, fatigue, impaired coordination, pain, etc. Though there is no permanent cure for MS but scientist and doctors around the world suggest that by blocking the immune cells and stopping them from crossing our blood brain barrier can prevent this disease.
Multiple sclerosis can also be prevented by stimulating the myelin to regenerate.
Answer:
-Reporter gene.
Explanation:
A reporter gene can be defined as a gene, which is used as an indicator to check uptake or expression of gene by a cell or organism. It is attached to a regulatory sequence of a different gene of interest in cell culture, bacteria, plants, or animals by the researchers and used to confer its expression in that organism or cell.
Gene for GFP (green fluorescent protein) is an example of reporter gene, due to which cells that express gene of interest emit green color under blue light.
As in given experiment, target gene (gene for rhodopsin) is attached with gene for GFP, it represents an example of reporter gene.
Thus, the correct answer is 'reporter gene.'
To learn and study the organisms that live in the surrounding areas. The native species could die or be destroyed by the non native species.
In moving from the outside environment to the inside of a bacterium, the first layer encountered would be Glycocalyx.
The cell coat or outermost layer of bacterial cells is called the glycocalyx. Glycoproteins, glycolipids, and proteoglycans make up its composition.
It is a network of lipids and membrane proteins connected by polysaccharide chains. On the lumen side, it encircles the vascular endothelial cells.
Various bacteria have varied glycocalyx layers with different compositions and densities. It serves as a protective layer and participates in cell interaction, signalling, and identification.
