The process is basically made up of transcription and translation. Transcription occurs first, and it involves the copying of genetic information from a DNA molecule to an mRNA molecule.

The process of transcription starts with the unwinding of the DNA double helix at a particular section to enable the copying of the bases to the mRNA. The bases are then copied in their complementary order,i.e C-G, A-U. The mRNA molecule contains Uracil in place of thyamine. Once the process is complete, the mRNA leaves the nucleus.

Translation occurs once the mRNA reaches the cytoplasm(ribosomes). A special type of RNA called the transfer RNA enables the translation process to occur. A set of three bases from the mRNA form a codon.example is AAC. The codon triplets are read by the tRNA, and one codon codes for a particular amino acid. There is always a start codon, one which is the first to be translated. Once all the codons have been translated, the stop codon is the last to be translated and it marks the end of the translation process.

The amino acids then form protein molecules
