The genome is the complete set of genetic material, including all of an organism’s genes, chromosomes, and non-coding DNA. Genes are segments of DNA that contain instructions for making specific proteins or other molecules.
Before a gene can be expressed, it must first be transcribed into a molecule called messenger RNA (mRNA). Transcription is the process by which an enzyme called RNA polymerase copies the DNA sequence of a gene into mRNA. The mRNA molecule is then transported out of the cell nucleus and into the cytoplasm, where it can be translated into a protein.
In the cytoplasm, the mRNA molecule binds to a structure called a ribosome, which is responsible for protein synthesis. The ribosome reads the mRNA sequence and assembles the correct sequence of amino acids to create the protein encoded by the gene. This process is known as translation.
Gene expression is a highly regulated process, with various mechanisms that control when, where, and to what extent a gene is expressed. These mechanisms include the binding of proteins called transcription factors to specific regions of DNA, as well as epigenetic modifications that can turn genes on or off.
