Verified step by step guidance
1
Understand that DNA contains the genetic instructions for the development, functioning, growth, and reproduction of all known organisms.
Recognize that the primary role of DNA is to store information that determines the sequence of amino acids in proteins.
Recall that proteins are made up of long chains of amino acids, and the specific sequence of these amino acids determines the protein's structure and function.
Note that the sequence of nucleotides in DNA is transcribed into mRNA, which is then translated into a specific sequence of amino acids during protein synthesis.
Conclude that while DNA influences many cellular processes, its direct role is in determining the sequence of amino acids in proteins, which in turn affects cellular functions such as energy production, cellular respiration, and membrane structure.
