* DNA Holds the Code: Genes are segments of DNA that contain the instructions for building a specific protein. These instructions are encoded in the sequence of nucleotides (A, T, C, G) within the gene.
* Transcription: The process of creating a protein begins with transcription. DNA's genetic code is copied into a molecule called messenger RNA (mRNA). The mRNA molecule carries the protein blueprint out of the nucleus.
* Translation: In the cytoplasm, the mRNA molecule is translated into a chain of amino acids. This translation process is carried out by ribosomes, which read the mRNA code and link the corresponding amino acids together.
* Folding into a Functional Protein: The chain of amino acids then folds into a specific three-dimensional shape, creating a functional protein. This shape is determined by the order of amino acids encoded by the gene.
In summary: Genes are the blueprints for proteins. They contain the instructions for creating the specific sequence of amino acids that determine the protein's unique structure and function.
