We want to detect a specific dna sequence, which for bees is least effective for that? a southern blot, gel electrophoresis, plimilarase chain reaction, or a microarray.
00:15
Okay, so let's get through these.
00:18
What does a microarray do? so a microarray, you get a chip that has a collection of dna spots, and these dna spots are of a specific sequence.
00:29
They have a probe sequence.
00:31
And they're intended to hybridize with the complementary dna.
00:36
So this can detect a specific sequence.
00:40
If you have the correct sequence in the array, it will hybridize to your specific sequence and you detected it.
00:45
Great.
00:46
So that is effective.
00:48
Plymerase chain reaction.
00:50
So polymerase chain reaction uses specially chosen primers to amplify a specific sequence...
