In the flow of genetic information, which sequence correctly represents the order?

• A. RNA > Proteins > DNA
• B. DNA > Proteins > RNA
• C. DNA > RNA > Proteins
• D. Proteins > RNA > DNA

Answer: (C)

The sequence that represents the correct flow of genetic information is DNA > RNA > Proteins. This process is known as the central dogma of molecular biology. In this sequence, DNA serves as the template for the synthesis of RNA in a process called transcription. During transcription, segments of DNA are copied into messenger RNA (mRNA), which then undergoes modifications before it leaves the nucleus. Once in the cytoplasm, the mRNA serves as a template for the synthesis of proteins in a process called translation. Ribosomes read the mRNA sequence and translate it into a specific protein by linking together the appropriate amino acids in the correct order. This accurate representation of the flow is foundational in genetics and molecular biology, illustrating how genetic information stored in DNA is ultimately expressed as functional proteins that perform various roles within organisms.
