Nevertheless, these examples illustrated how the code is transcribed from DNA to mRNA and how the mRNA is then translated in order to specify the sequence of amino acids in a particular protein which is the product of that particular gene on a chromosome.

Two of the 46 chromosomes, known as X and Y, are called sex chromosomes because they help determine whether a person will develop male or female sex characteristics. He thus saw a large number of individuals with developmental variations.
