Let us look at the components of crispr's array.
00:08
The first component is the crispr's array.
00:14
So it is a section of dna which is contained in the genome of a certain bacteria or archaea.
00:21
It is a short section which has repetitive sequence with repetitive sequences in a bacteria.
00:38
And they contain specific sequences known as spacers.
00:44
These spacers are derived from genetic material obtained from previous encounters with foreign genetic elements.
00:58
So spacers are short repetitive sequences which are derived from genetic material obtained from previous encounters such as viruses.
01:11
The next component is the cas9 protein.
01:16
The cas9 protein is an endonucleic enzyme which is derived from the bacteria specially from the crispr associated system.
01:26
So the cas9 protein is the crispr associated system which is known as cas.
01:33
And this system helps by cutting the dna at specific target sites.
01:42
Cas9 acts as a molecular scissor that can be guided to the desired dna sequence through a guide rna.
01:52
Next we have the guide rna or the grna.
01:58
The guide rna is an engineered rna molecule that contains two main components...
