To make a protein, a gene’s DNA sequence is transcribed to a strand of RNA. Then the RNA is translated into a chain of amino acids by a ribosome, and a protein is formed. DNARNAProteinTranscriptionTranslationRNADNA must be transcribed into RNA before it can become a protein. Instead of the base pairs being A-T, and G-C, the base pairs for RNA are A-U, and G-C. This is the major difference between RNA and DNA. Once the mRNA is built off of the DNA strand inside the nucleus, the mRNA can then travel into the cytoplasm where it undergoes translation.AAAAATTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTAAAAAAAAAAAAAAAAAAAAAAAAAAGGGGGGGGGGGGGGGGGGGCCCCCCCCCCCCCCCCCCCCUUUUUUUUUUUUUUUUmmmmmmmmmmmmmRRRRRRRRRRRRRRRRNNNNNNNNNNNNNNNNNNNNAAAAAAAAAAAAADNAProteins in cells act as messengers and help to determine the traits of an orgggggggaaaaaaaaaaaaaaaannnnnnnnnnnnnnnnniiiiiiiiiiisssssssssssssmmmmmmmmm such as ttttttttttttthhhhhhhhhhhhhhhhhhheeeeeeeeeeeeeee ddddddddddddddddifferrrrrrrrrrrrreeeeeeeeeeeeeeeeeeennnnnnnnnnnnnnnnntt shapes, sizes, colors and other features found in living organisms.
