C.Central nervous system effect
***the molecular tools are:
Restriction enzymes
Restriction genes allow the synthesis of DNA-cleaving endonucleases at very specific sites to digest parasite DNA
-RNAse
* RNA A: specifically cleaves single-stranded RNAs, and releases residues of pyrimidine 3'-phosphates
* H RNA: cleaves DNA / RNA hybridization -digests RNA in an RNA-DNA complex. It is used to remove RNA after making a first strand of cDNA using reverse transcriptase.
-Alclaline phosphatase:
Alkaline phosphatases are active at alkaline pH. They make it possible to remove the phosphate group situated at 5 'of a DNA chain. They are extracted from bacteria or animal origin (intestines). They are used to prepare recombinant DNA.
-Kinase:
Kinases make it possible to fix a phosphate group in the presence of ATP.
-the enzymes copying the nucleic acids:
* DNA Polymerase (Taq, and the Klenow fragment) for example)
* inverted transcriptase.
* RNA polymerase
-Ligase
***Use of these techniques.
The biologist has a number of tools and methods for studying gene mutation. The analysis of the gene will make it possible to diagnose certain pathologies. Then, once the pathology is known, the doctor can establish an adequate treatment for the patient in order to treat it.
The nervous system consist of the brain spinal cord and the brain .
Peripheral proteins are held to the membrane surface primarily through electrostatic or hydrogen bonds.
1) The antibodies destroy the antigen (pathogen) which is then swallowed and digested by macrophages.
2) White blood cells can produce antitoxins which destroy the toxins that are otherwise known as poison.
