Information Transfer

Definition

In biology, information transfer refers to how genetic information passes from DNA to RNA and then directs the synthesis of proteins.

Analogy

Information transfer is like a game of telephone. DNA whispers the message (genetic information) to RNA, who then passes it on to the protein-making machinery in our cells.

Transcription: This is the process where genetic information from DNA is copied into mRNA - it's like taking notes from a lecture.

Translation: This is when mRNA's message gets decoded to build a protein - think about translating a foreign language into your native tongue.

Gene Expression: 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.
