Hi guys, over here we have been asked that we have to discuss that how the human impact on the environment will result in change in an organism's genetic material or the dna and how it can alter the growth and reproduction of the integration.
00:17
Also, we have to give an example of such an organism.
00:21
So if we talk about the dna, dna is what? dna is the genetic material, yes, or you can say editing material, that is responsible for transferring the information.
00:31
That is the information of hereditary.
00:34
Yes, so hereditary information will pass by the rna or the dna.
00:38
Yes, so it will store the genetic information.
00:41
They are storage molecules for it, yes.
00:43
So you have to understand that they will be used to control nearly all the aspects of life from growth.
00:53
Yes, from you can think of growth as well as it can also affect the reproach.
01:02
Process.
01:04
Yes, so it will control everything.
01:05
Also, you can say that's why, therefore, if we alter the dna, yes, if there is any alteration of what, alteration of the genetic material, that is the dna.
01:19
So you can say that it will result to change in the phenotype or mistaken phenotype, altered phenotype of the living organism.
01:29
Yes, this is very important.
01:31
You have to remember fine if you move towards the factors yes so uh factors uh that can alter the dna yes so here if you talk about these factors then these factors are known as the mutagens what are these mutagens mutagens are basically the substances or some factors that can lead to the mutation yes so these will uh you can say change some sequence of the amino acids in the dna, yes.
02:06
So here you can say that these are called as mutagens and also there are many mutagens which are seen in environment that can directly result from the activities of humans.
02:19
So humans are basically main cause of all of these.
02:23
Also, the uv rays, yes, or the uv rays or you can say the solar radiations are also mutagens.
02:32
Also, the smoke from the cigarette is mutation and also the alpha and the gamma rays.
02:40
Yes.
02:41
Also, there are some of the chemicals which can add as the mutagens...
