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...
