What is the flow of information in the synthesis of proteins?

The correct flow of information in the synthesis of proteins is from DNA to RNA to protein. This process is often referred to as the "central dogma" of molecular biology.

In this sequence, DNA serves as the template for the synthesis of RNA during a process called transcription. In transcription, specific segments of DNA are copied into messenger RNA (mRNA). Once mRNA is synthesized, it undergoes processing and is then translated into a protein during the process of translation. During translation, ribosomes read the mRNA sequence and assemble the corresponding amino acids to form a protein.

This sequential flow is crucial for the expression of genes and the production of proteins, which are vital for the structure, function, and regulation of the body's tissues and organs. Understanding this flow is essential for grasping how genetic information is converted into functional products in living organisms.
