Homework Answers
Answer 4. Option 1, radiolabeled ssDNA fragments used to visualize..
In microarray, thousand of short strands of ssDNA are embedded as probes. These probes are manufactured artificially from the known genes. Each probe has a unique nucleotide sequence that is complementary to the target mRNA sequence.

The picture above represents an agarose gel that was used to analyze plasmid DNA after it was cut with the restriction enzyme HindIll. The plasmid was incubated with Hindill until all of the available Hindlll cut sites were cut by HindIll. After running the sample on the gel, three bands were detected (Note that there are three wells shown at the top of the gel for loading samples, however, only the middle well was loaded with sample). Based on this...
