* Genes: DNA is organized into segments called genes. Each gene contains the instructions for building a specific protein.
* Codons: The sequence of nucleotides (A, T, C, G) in a gene is read in groups of three called codons. Each codon codes for a specific amino acid.
* Amino acids: Amino acids are the building blocks of proteins.
* Protein synthesis: The DNA code is transcribed into messenger RNA (mRNA), which carries the instructions to the ribosomes. Ribosomes use the mRNA code to assemble the correct sequence of amino acids, forming a protein.
What proteins do?
Proteins perform a vast array of functions within your body, including:
* Enzymes: Catalyze (speed up) chemical reactions.
* Structural components: Provide shape and support to cells and tissues.
* Hormones: Act as chemical messengers.
* Antibodies: Help fight off infections.
* Transport proteins: Move molecules across cell membranes.
* And many more!
Essentially, DNA provides the blueprint for creating all the proteins that your body needs to function properly.
