Genetic technologies.
00:03
First, let us understand what do we mean by this genetic technologies.
00:11
We know every organism is made up of genes.
00:18
Basically, the genes are the blueprint of any organism or any species also we can say.
00:27
Now, if we are able to study the genetics of a person, we can to some extent explain the functioning of an organism.
00:42
Even in evolution, genetics is used.
00:46
Now, according to the question, genetic technologies have improved our understanding of biology and have aided the advancement of human medicine.
00:59
To understand this statement, let us take a very recent example of covid -19.
01:10
We know covid is caused by coronavirus.
01:15
It is a virus caused organism.
01:20
Now, to identify whether a person is infected with covid or not, initially the tool that was used is known as pcr that is polymerase chain reaction.
01:37
In this, it is basically an amplification process.
01:44
We amplify the genome just to identify whether the genome of the virus is present along with our dna or not.
01:54
If present, that means that person is suffering with covid or infected by coronavirus.
02:01
So, pcr is one of the genetic technology that we are using...
