Question #1
The final 60 minutes extension is purposed to assist in the initiating process of the
addition of untemplated products of A with its products of 3. A final rest is then provided to
assist the enzymes to complete its untemplated polyadenylation. However, when sufficient time
is not provided to add adenosine to every copy of PCR, there will be a few fragments that are one
base pair shorter compared to others. Lack of sufficient during down-streaming could generate
issues of data interpretation (Alaeddini, 2018).
Question #2
A primer that is well-designed forms the most significant element of a good PCR
reaction. Primers are synthesized chemically by the union nucleotides. Three main steps which
followed when designing PCR that includes denaturation, annealing, and extension. The first
step involves the denaturing of genetic m...
