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 three bands?

#Unit 13. Methods in Biology
  1. The more repeats you have, the longer your DNA fragment is, and longer DNA fragments migrate more slowly in gels.
  2. They are heterozygotes at this region.
  3. They are homozygotes at this region.
  4. They are heterozygotes, and possess one allele that can be cut and one allele that cannot be cut.

ROS using respiratory burst oxidase homolog (RBOH) or NADPH  oxidase for Self- generation mechanism by some other processes , which are involved in ROS generation such as,
A) The amino-terminal cytoplasmic domain of RBOH proteins contains four serines (Ser) that can be phosphorylated by CDPKs and two EF hands that can bind calcium directly 
B) As ROS generation such as  H2O2,  by putting electron for oxidising  oxygen into the free radicals, these electron generation by oxidising NADPH and FADH2 in the cytosolic carboxy terminal of RBOH protein
C) The elevation of calcium and ROS levels during the early stages of the stress response activates protein kinases and phosphatases
D) ROS activated Ca2+ channel leads to Ca2+  influx from apoplastic space  to cytosol
Arrange the correct order of  following steps involve in ROS generation;
