Lecture 3.4 Information Transfer in Biology — Translation
HAZEL SIVE: We're well along our sequence of molecular information transfer. The thing that I want to talk with you about now is kind of the culmination of information transfer. And that is the process of translation. Translation refers to a process that produces protein from an RNA template. If we think about DNA replication and transcription, they are, in a way, quite similar. DNA replication is just copying one language into the same language. Transcription is kind of like changing fonts in your Word document. You go from Calibri to Georgia. The letters are the same. You can recognize them. There's a U, the UT, thing. But otherwise, the letters are the same. You're in the same language with RNA transcription from DNA. Translation is different. We're producing a protein here that's made of amino acids, its own language, from a different language, the language of nucleic acids. And that sense of how does nucleic acid encode protein, a different langua...
