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.
  

Given the data so far, for which of the following statement is correct

#SCPH05 I Biotechnology
  1. Baby A is legitimate child of given parents because it has a band @ n=25 and there is only one set of parents that could have given a chromosome 15 with n=25 to their offspring, couple #3
  2. Baby B is legitimate child of given parents because it has a band @ n=25 and there is only one set of parents that could have given a chromosome 15 with n=30 to their offspring, couple #2
  3. Baby C is legitimate child of given parents because it has a band @ n=30 and there is only one set of parents that could have given a chromosome 15 with n=25 to their offspring, couple #1.
  4. Baby A is legitimate child of given parents because it has a band @ n=35 and there is only one set of parents that could have given a chromosome 15 with n=35 to their offspring, couple #3.

Chlorophylls a and b are abundant in green plants, and c and d are found in some protists and cyanobacteria. A number of different types of bacteriochlorophyll have been found; which type of chlorophyll is the most widely distributed, shows the distribution of pigments in different types of photosynthetic organisms;
