Homework Answers

Answer #1

For the amplification of DNA, two primers are always required. One is called the forward primer and the other one is called the reverse primer. Forward Primer binds to the start of template strand (anti-sense strand) while the Reverse primer binds to the end of complementary strand (sense strand). These primers are always complementary to the nucleotide sequences of beginning and terminal sections of DNA to be amplified respectively. The primers always bind to the edges of the sequence to be amplified.

As a reminder, PCR is the technique used to replicate DNA in the lab. PCR is based on the way DNA is replicated in cells. During PCR template DNA plus other ingredients are placed in a test tube and the solution goes through repeated cycles of heating and cooling. You can find more information about PCR here. The 'ingredients' of a basic PCR reaction are: DNA template, primer, nucleotides, DNA polymerase, and any salts required for polymerase function (buffer). No...
