Carbon emissions are responsible for the global warming crisis. More specifically they are responsible for bad air quality. Greenhouse gases. Sometimes also cancers
The right answer is D.
A codon is a sequence of three nucleotides on a messenger ribonucleic acid (mRNA) specifying one of the 22 proteinigenic amino acids whose succession on the messenger RNA determines the primary structure of the protein to be synthesized. As the messenger RNAs consist of a succession of several tens to several hundreds of nucleotides, it is also several tens to several hundreds of amino acids that can thus be assembled linearly to form protein chains.
