Answer 17:During embryonic or foetal development in the mother
Answer 18: After fertilization, before transfer of embryo to the mother
Answer 19: Choice e (first 3-4 cycles of the PCR are required for primer annealing and homogenization, after which the desired amplicon is generally produced)
Answer 20: Choice a (the Alu repeats represent short tandem repeats which are genetically inherited in humans. Their length may reach upto 300 base pairs in the DNA)
