For dna sequencing, it is done by bringing a long strain of dna into multiple tiny fragments.
00:20
And we can sequence each fragment using single sequencing method to determine the nucleotide sequences of this fragment.
00:36
And then after that, we can combine them together.
00:38
And compared to the reference sequence, we are able to find out the variation in the test sample.
01:06
And this variation can be mutations.
01:11
And some of the mutations are okay and some of the mutations are not really.
01:17
So the healthcare professionals can look at this mutation and give advice whether the regime is okay or they are defective, which could be.
01:28
To lead to diseases such as cancer.
01:36
On the other hand, for microarray, it is again a lead to.
01:47
So for microarray, typically are microscopic slides that are printed with thousands of tiny spots in the defined position.
01:58
So let's say this is a microarray slide and there are tiny sports printed on it.
02:05
And for each spot, there is a specific probe attached to it...
