With the help of DNA fingerprinting which can be used to determine paternity. There are three babies (Baby A, Baby B and Baby C) in a maternity ward, and three sets of confused and worried parents. (Father and Mother #1 are a couple, as are Father and Mother #2, and Father and Mother #3.)
You do each PCR reaction on chromosome 15 and load each one into a separate well of an agarose gel, and then run the gel.

Why is it that some people show two bands?

A scientist conducts an experiment to determine the rate of the following reaction:

N2(g) + O2(g) → 2NO(g)

If the initial concentration of N2 was 0.500 M and the concentration of N2 was 0.450 M after 0.100 s, what is the rate of the reaction?
