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 answer is letter A.DNA. Proteins are made up of 20 amino acids all coded by DNA! DNA makes up who you are. DNA is the nucleic acid which provides the master code for protein synthesis. Most DNA molecules consist of two biopolymer strands coiled around each other to form a double helix. Comments
