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.
How do nucleotides in the RNA molecule code for various amino acids How many nucleotides code for one amino acid? Each nucleotide is made up of an organic base, a pentose sugar and a phosphate. Nucleotides can be arranged in various different orders and that order dictates which amino aci â¦ d it codes for, three amino acids code for one nucleotide.
