Answer:
Chromosome structure consists of a long arm region and a short arm region connected at a central region known as a centromere. The ends of a chromosome are called telomeres. Duplicated or replicated chromosomes have the familiar X-shape and are composed of identical sister chromatids.
Explanation:
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.
Answer: It is a technique used to amplify a segment of DNA of interest or produce lots and lots of copies. In other words, PCR enables you to produce millions of copies of a specific DNA sequence from an initially small sample – sometimes even a single copy. (looked it up on google lol)
