Guida verificata passo dopo passo1
Understand that DNA contains genetic information in the form of sequences of nucleotides (A, T, C, G).
Recognize that this sequence of nucleotides is transcribed into messenger RNA (mRNA) during gene expression.
Know that the mRNA sequence is then translated into a sequence of amino acids, which fold to form proteins.
Recall that proteins are the molecules that perform most cellular functions and determine the structure and function of cells.
Conclude that DNA codes for the sequence of amino acids in proteins, which ultimately affects the traits and functions of living organisms.
