In 3–5 sentences, construct a summary of the process of gene expression, starting with DNA and ending with proteins..

Gene expression begins with DNA in the nucleus of a cell being transcribed into mRNA by RNA polymerase. The mRNA then travels to the ribosomes in the cytoplasm, where it is translated into a protein by ribosomes using tRNA molecules. The tRNA brings amino acids to the ribosomes, where they are joined together in the order specified by the mRNA to form a protein. This protein then undergoes folding and modifications to become functional in the cell.

Gene expression starts with DNA in the cell's nucleus. It gets copied into a message called mRNA. This mRNA moves to the ribosomes in the cell where it guides the building of proteins. The ribosomes read the mRNA code and link the correct amino acids together to form a protein. The protein then folds and is ready to do its job in the cell.
