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

#SCPH01 Biochemistry
  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.

 A mutated E. coli cell carries out and completes DNA replication, but the lagging strands are found to contain more errors than normal. These errors are not found evenly distributed throughout the lagging strands, but are found in clusters. Which enzymatic activity is missing from this cell?
