You have a portion of a bacterial chromosome that you are studying. In this portion there are four protein-coding genes, all controlled by one promoter. Required:
a. How many transcripts are expected from this region?
b. How many polypeptides are expected?
c. How many true start codons are expected?
d. How many true stop codons are expected?
e. If there is a repressor binding site, where do you expect to find it?

Two students are working together on an experiment that measures the effect of different liquid fertilizers on the thickness of plants’ stems. which is most likely to result in the greatest amount of error in their scientific experiment? a.one student measures the plant stem widths by using calipers. the other student measures the widths of the same plant stems again by using a different pair of calipers. b.one student measures the plant stem widths by using calipers. the other student types the measurements as they are taken into a computer spreadsheet. c.one student weighs liquids for the experiment by using a calibrated scale. the other student weighs liquids for the experiment by using a different calibrated scale.
