Answer:
An organism's DNA affects how it looks, how it behaves, and its physiology. So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation. Without modification, growth could not occur. i hope this help
Explanation:
The hole in the Ozone Layer
The answer is Question, because they need to find a question before they could do a research. Because they don't even know what to research on.
***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.
