Expression of Genetic Information topics include: Genetic code, RNA viruses and reverse transcription.
Gene expression is the process of turning genetic information into a function. It involves two major steps: transcription and translation.
Transcription is the DNA-directed synthesis of RNA. During transcription, the information stored in a gene's DNA is passed to a similar molecule called RNA (ribonucleic acid) in the cell nucleus. Translation is the conversion of genetic codes from the DNA code into a protein. Gene expression is vital for maintaining normal cellular structure and function. It is also the basis for developmental changes, such as differentiation and morphogenesis. The physical expression of a gene is called the phenotype.
