cDNA from the mRNA are used. In the wells, there are single strand DNA not RNA.

I have a confusion about the radio labeling (yellow dots & blue dots) how is it done ? How can one know whether one is a cancer cell or normal cell in the first place ?
@cdorman11
@cdorman11 2 года назад
As to the second question, it's the same as knowing where to take the biopsy from. It's what's growing rapidly, and showing up as dense tissue in an X-ray.

Great video. But, in my textbook it says that the wells are filled with DNA, not mRNA.

There are different kinds of microarrays -- gene microarrays (DNA) and gene-expression microarrays (mRNA).

In the well, would their be complementary RNA, or ssDNA complementary to the probed cDNA ?
@mikell.6064
@mikell.6064 5 лет назад
The video was very poorly explained. The well doesn't contain RNA. It contains ssDna that hybridizes with complementary DNA from sample. The sample is obtained from reverse transcribing the RNA from the cell to cDNA. This CDNa is used to hybridizes with the well. So in short the answer to your question is ssDNA
