A cell interprets the genetic code through codons in the mRNA, which are sequences of three nucleotides in a row. These codons determinate an amino acid, the only exception is the stop codon. The starting point in the translation process is AUG codon. Based on these nucleotide sequences, tRNA with adequate anticodons adds amino acids in order to make polypeptide molecules. The translation process is completed when the stop codon is reached.

A mRNA molecule enters the ribosomes, where transfer RNA attaches to it. A mRNA molecule is built of codons, which are sequences of three nucleotides in a row, which determinate an amino acid. The starting point in the translation process is AUG codon. Based on these codons, tRNA with adequate anticodons adds amino acids in order to make polypeptide molecules. The translation process is completed when the stop codon is reached.

Genes represent sequences of nucleotides based on which proteins are synthesized. This includes the processes of transcription, when mRNA is formed, and translation, during which tRNA add adequate amino acids which are then binded into polypeptides with help of rRNK. Thus, genes are the code, while proteins are the final product.

DNA molecule contains information for coding proteins. This information is passed on the mRNA during a process of transcription. A large diversity among genes is followed by a large amount of various mRNA molecules. However, ribosomes consist of rRNA, which is included in the process of translation. The smallest of the three types of RNA is tRNA, which has only 75 to 95 nucleotides and has a role in bringing particular amino acids to the growing polypeptide. We can conclude that mRNA contribute to the diversity of polypeptide molecules because it carries an information about their synthesis.

All living creatures contain genetic information stored in the DNA and RNA molecules. Genes are built in the same way in prokaryotic and eukaryotic cells. Genes are composed of nucleotides, while three nucleotides in a row make a codon. There are about 64 codons for 20 amino acids and they are universal, which means that a codon for certain amino acid is the same in every organism. This universality reveals us a shared past among all organisms.

DNA is a molecule that contains the whole genetic code of an organism. Based on nucleotide sequences of these genes, particular proteins are made in ribosomes of a cell. Proteins affect the function of a cell on a molecular level, which causes a certain characteristic to develop.
