Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the Central Dogma of Genetics?
A
DNA encodes mRNA and mRNA makes proteins
B
tRNA encodes DNA and DNA makes proteins
C
tRNA brings in anticodons and codes proteins
D
None of the above
Explanation: 

Detailed explanation-1: -The central dogma of molecular biology describes the flow of genetic information in cells from DNA to messenger RNA (mRNA) to protein. It states that genes specify the sequence of mRNA molecules, which in turn specify the sequence of proteins.

Detailed explanation-2: -Central dogma. The central dogma of molecular biology is a theory stating that genetic information flows only in one direction, from DNA, to RNA, to protein, or RNA directly to protein.

Detailed explanation-3: -The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.

Detailed explanation-4: -The central dogma suggests that DNA contains the information needed to make all of our proteins, and that RNA is a messenger that carries this information to the ribosomes?. The ribosomes serve as factories in the cell where the information is ‘translated’ from a code into the functional product.

Detailed explanation-5: -The classic view of the central dogma of biology states that “the coded genetic information hard-wired into DNA is transcribed into individual transportable cassettes, composed of messenger RNA (mRNA); each mRNA cassette contains the program for synthesis of a particular protein (or small number of proteins)."
