Detailed explanation-1: -DNA reads and translates the RNA code: RNA is the one that reads and translates DNA.

Detailed explanation-2: -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-3: -During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA (Figure 1).

Detailed explanation-4: -There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

Detailed explanation-5: -Portions of DNA Sequence Are Transcribed into RNA The information in RNA, although copied into another chemical form, is still written in essentially the same language as it is in DNA-the language of a nucleotide sequence.
