The answer is true. During translation of mRNA, the nucleotides are read by the translation unit (ribosome and trna) in sequences of three (3). These sequences are referred to as codons. Codons code for amino acids. Some codons are start of stop codons meaning they initiate or terminate translation. Additionally, more that one codon could code for one amino acid.
The type is off in a couple of places with half of the lines shifted over one space, so it makes it hard to read. Check the pic.
