Question

research scientists isolate proteins in a ph gradient. separation of protein a, protein b, and protein c in a ph gradient how many proteins recorded protein activity greater than 6 units in at least 3 samples? a. 0 b. 1 c. 2 d. 3

Explanation:

Step1: Analyze Protein A

For Protein A, count the number of samples where activity > 6 units. We can see from the graph that Protein A has activity > 6 units in more than 3 samples.

Step2: Analyze Protein B

For Protein B, count the number of samples where activity > 6 units. Protein B has activity > 6 units in more than 3 samples.

Step3: Analyze Protein C

For Protein C, count the number of samples where activity > 6 units. Protein C has activity > 6 units in more than 3 samples.

Answer:

D. 3
