The burning of fossil fuels by humans is the largest source of emissions of carbon dioxide, which is one of the greenhouse gases that allows radiative forcing and contributes to global warming.
The genetic code. Efforts to understand how proteins are encoded began after DNA's structure was discovered in 1953. George Gamow postulated that sets of three bases must be employed to encode the 20 standard amino acids used by living cells to build proteins, which would allow a maximum of 43 = 64 amino acids.
The genetic code dictates which proteins the cell manufactures. Proteins are strands of amino acids. The sequence of nucleotides in DNA genes determines the order of amino acids in a protein.This is the direct connection between your genes and your traits.he genetic code dictates which proteins the cell manufactures.
