Please explain the following question and answer all


29. The central dogma of molecular genetics is that DNA encodes an mRNA, and mRNA allows proteins to be made. In the lecture on making cDNA libraries there was a statement that jokingly) said “central dogma be damned”. What is it about making a cDNA library that goes against the central dogma? A. although a primer is required to make a cDNA, the primer is simply a long run of “T’s”, B. the resulting cDNA doesn’t have any introns, but the DNA for a eukaryotic gene would C. the enzyme reverse transcriptase reverses the flow of information by going from mRNA D. the construction of a cDNA library does not require a protein intermediate, the central so the primer is not really specific have introns to cDNA dogma involves DNA, mRNA, and proteins.
