Question

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.

Answer 1

29) cDNA to build libraries that contained DNA copies of mRNA from cells and tissues.

ANSWER IS D

30) Answer is C

Mutations in the HEXA gene cause Tay-Sachs disease. The HEXA gene provides instructions for making part of an enzyme called beta-hexosaminidase A, it plays a critical role in the brain and spinal cord.development

Beta-hexosaminidase A helps break down a fatty substance called GM2 ganglioside.
