A researcher is attempting to use RNAi to investigate the function of citrate synthase, an enzyme that is involved in the Kreb's cycle. If the researcher injected siRNAs complementary to citrate synthase mRNA into cells, what is the most likely outcome that she would observe?
Q55 Q55 Q55
DNA microarrays can be used to determine relative levels of gene expression between samples. DNA microarrays are usually interpreted by color: green means higher mRNA levels, yellow means equal levels, and red means lower levels. If you ran the samples from the temperature experiment on a DNA microarray using the 25°C experiment as a baseline, what results do you predict you would obtain?
