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?

#Section 7: Recombinant DNA technology and Other Tools in Biotechnology
  1. The more repeats you have, the longer your DNA fragment is, and longer DNA fragments migrate more slowly in gels.
  2. They are homozygotes for the allele that cannot be cut.
  3. They are homozygotes for the allele that can be cut.
  4. They are heterozygotes, and possess one allele that can be cut and one allele that cannot be cut.

How light controls the assembly of chloroplast enzymes into supramolecular complexes?

a.) Light regulates the stability of the ternary complex through the ferredoxin–thioredoxin system

b.) Reduced thioredoxin cleaves the disulfide bonds of both phosphoribulokinase and CP12, releasing glyceraldehyde-3-phosphate dehydrogenase and phosphoribulokinase in the catalytically active conformations

c.) Oxidised thioredoxin cleaves the disulfide bonds of both phosphoglyceratekinase and CP12, releasing glyceraldehyde-3-phosphate dehydrogenase and phosphoglyceratekinase in the catalytically active conformations

d.) thioredoxin system oxidised the disulfide bonds and reduces the assembly of between chloroplast enzymes and CP12 and converted into the catalytically active conformations
