Answer:

b. 80g

Explanation:

Three cycles of PCR would produce 3 doublings of the amount of DNA.

Cycle 1: 10x2  = 20pg

Cycle 2: 20x2 = 40pg

Cycle 3: 40x2 = 80pg

This can also be worked out for large cycle numbers by final mass = starting mass x 2ⁿ, where n is the number of cycles.

Vikentia [17]
