DNA → RNA → Proteins is the correct sequence of flow of genetic information in a cell.
What are genetic information?
- These are the information that are stored in the DNA (genetic material) of an organism.
- They are expressed in the form of proteins that can have different functions like enzyme, hormone, transcriptional regulators, etc.
How is genetic information expressed?
- DNA is used to form a mRNA (Transcription) in the nucleus and is transferred into the cytoplasm.
- In cytoplasm this is read by ribosomes and a protein is synthesized according to the codons of mRNA (Translation).
- Some organisms that have RNA as their genetic material: the RNA forms a DNA molecule (Reverse transcription) and then the same steps are followed.
