The genetic code refers to the order of nucleotides that make up a person's DNA or RNA, and this provides the blueprint for life, as well as a set of instructions for how to create proteins. Discover how genetic encoding results in the creation of physical traits with help from a science teacher and field biologist in this free video on biology.

Hi, I'm Brian with ericksontutoring.blogspot.com. Today we're going to discuss and define genetic encoding. So the genetic code is the, refers to the nucleotides and the order of nucleotides that make up your DNA or RNA. And basically this provide the blueprint for life and more, in more detailed, they provide a set of instructions for how to create proteins. So nucleotides sequences are generally read in groups of three called triplets and each group of three is called the codon. So since there's four different nucleotides, you, you can, you have four options for what goes in your first spot; four options for what goes in the second and again four options for what goes on the third. So four to the third power, sixty four; so there's sixty four different codons that might be formed and these generally code for twenty amino acids. And then an amino acid, when you put those in the long chain, those end up forming proteins which do all sorts of great and necessary functions in a body. So genetic encoding is simply referring to the order of the nucleotides that make up the genetic code forming the proteins and thus, creating a lot of the physical traits and other things that we see in organisms.
