Question

A scientist has a sample of protein and a sample of nucleic acid, but the labels

have fallen off the test tubes.
Which of the following tests would be useful in correctly identifying the
samples? Select all that apply.
A. Determine the amount of nitrogen in each sample.
B. Determine the amount of phosphorus in each sample.

C. Determine the total number of monomer molecules in each sample.
D. Determine the number of different types of monomers in each sample.

Answer 1

A and B

Step-by-step explanation:

A and B are useful in correctly identifying the samples as the nitrogen content can be used to determine if the sample is a protein, and the phosphorus content can be used to determine if the sample is a nucleic acid. These two tests would allow the scientist to differentiate between the two types of biomolecules.

Answer 2

B. Determine the amount of phosphorus in each sample.

D. Determine the number of different types of monomers in each sample.
