How are genes used by cells to build proteins?

Question

Quizplus · Accepted Answer

Genes in DNA are transcribed into RNA molecules by RNA polymerase, which then direct the synthesis of proteins through the process of translation. The RNA molecule serves as a template for the synthesis of a specific sequence of amino acids, which are linked together to form a protein. This process is known as the central dogma of molecular biology, which states that DNA is transcribed into RNA, and RNA is translated into protein. Option B is incorrect because genes are always found in DNA and not RNA. Option C is incorrect because RNA molecules cannot directly synthesize proteins without the aid of ribosomes and transfer RNAs. Option D is incorrect because DNA is not directly translated into an amino acid sequence, but rather transcribed into an RNA molecule that is then translated into a protein.
