What molecule determines many of your traits?
Biology of the Molecule. This chapter focuses on DNA and proteins, and specifically how the "instructions" in DNA are used to make proteins. This model depicts a protein binding to DNA. Notice the "spiral staircase" shape of the DNA molecule, with the globular wrapped protein around it.
Molecular Biology focuses on DNA and how proteins are made. DNA contains the information used to make RNA. RNA leaves the nucleus and, together with a ribosome, makes proteins. The genetic code is the universal code that all life uses to turn the language of nucleotides into the language of amino acids. Mistakes in the DNA or RNA sequence can have dangerous consequences for the organism, though these same "mistakes" are the driving force of evolution. Regulating the specific timing of genes is an important process for cells in every organism to function properly.
