Genetic Code, Large Print-Braille
The genetic code is the set of rules by which information encoded within genetic material (DNA or mRNA sequences) is translated into proteins (amino acid sequences) by living cells.
These large print/braille sheets are embossed and printed on 11.5 x 11 inch 90# paper and contain four pages per set. Each set contains a separate page for nucleotide codons or triplets beginning with the letters A, U, C, and G, and the amino acids for which they code. Ten sets per pack are enclosed in a plastic envelope with a hook and loop fastener.

The genetic code consists of 64 three-letter “words” or “codons” that use a four-letter nucleotide alphabet: A, U, C, and G. Each three-letter codon is translated to one of 20 amino acids or a stop signal. For example, the codon AUG codes for the amino acid methionine, and the codon UUU codes for the amino acid phenylalanine. In this way, a sequence of DNA nucleotides is translated to a particular sequence of amino acids. During the translation process, amino acids are linked together to form proteins. Proteins are involved in cellular activities such as enzyme proteins needed for chemical reactions; structural proteins such as keratin and collagen found in hair, nails, and skin; hemoglobin in red blood cells needed for oxygen delivery to cells of the body; and antibodies that provide protection against disease.
