Sickle cell anemia is a genetic disease that affects hemoglobin. A single nucleotide change in the hemoglobin gene causes an amino acid substitution in the hemoglobin protein from glutamic acid to valine. The resulting proteins stick together to form long fibers and distort the shape of the red blood cells.
The information required to build resides on the in the form of sequences of , and has the form of triplets of bases called "codons" following the . Once the genetic information describing how to build a is to , it has to be "translated" into the "language" of the protein. The sequence of on the RNA forms a code for the building blocks of the protein. The word "translation" seems particularly appropriate for this process since the information contained in the DNA is translated from the four-character alphabet of the bases to the twenty-character alphabet of the amino acids.

A variety of engaging animations, lecture clips, virtual labs, and other classroom resources teach key concepts related to DNA’s structure and function.
The construction of the proteins is carried out on the of the host . There are free floating ribosomes where proteins are built for functions in the cytoplasm. Those proteins which are to be used as part of the cell membrane or transported outside the cell are manufactured on ribosomes which are attached to the .

The process of translation can be divided into the stages of initiation, elongation, and termination. Initiation involves at least three other proteins called initiation factors to help bind the mRNA to the smaller subunit of the two-unit ribosome. It is bound to the correct location using the initiation codon AUG on the mRNA. The next phase is elongation, or adding other amino acids to the building polypeptide chain. According to Karp, a step of elongation can be accomplished in about 1/20 second, so a small protein of 400 units could be assembled in about 20 seconds! It is suggested that most of this time is used sampling the amino-acid-carrying tRNAs in the cytosol to find the ones for which there is a codon-anticodon match for the next codon along the mRNA pattern.
From animations showing the details of DNA replication and transcription, to lecture segments that discuss DNA sequencing and PCR, and online interactives showing what sequence information reveals evolutionary relationships, BioInteractive provides a wealth of resources for teaching about DNA.
