In biology, information transfer refers to how genetic information passes from DNA to RNA and then directs the synthesis of proteins.
This is the process where genetic information from DNA is copied into mRNA - it's like taking notes from a lecture.
This is when mRNA's message gets decoded to build a protein - think about translating a foreign language into your native tongue.
The overall process by which genetic information flows from genes to proteins; how our traits are expressed - this would be like telling someone what you learned from that lecture.
