A series of codons in part of a messenger RNA (mRNA) molecule. Each codon consists of three nucleotides, usually representing a single amino acid. The nucleotides are abbreviated with the letters A, U, G and C. This is mRNA, which uses U (uracil). DNA uses T (thymine) instead. This mRNA molecule will instruct a ribosome to synthesize a protein according to this code.

Sickle Cell Anemia: An autosomal recessive inheritance caused by a point mutation of the hemoglobin beta gene (HBB) that affects the oxygen carrying pigment in red blood cells, hemoglobin. Changes in the hemoglobin-A chains of the red blood cells causes an alteration of the normal biconcave disc shape into the characteristic sickle cell shape.
