MAKING RNA Transferring genetic code (DNA) to RNA = Transcription Think of a medical transcriptionist copying the physicians words into another format. Where does transcription occur in prokaryotes? Eukaryotes? MAKING PROTEINS Making proteins = ______________. Think of how translation relates to languages. The translation of biology translates DNA information into proteins .

Translation & The ________ _______ _____________ (which contain rRNA) make proteins from the messages encoded in mRNA. The genetic instructions for a polypeptide chain are ‘written’ in the DNA as a series of 3-nucleotide ‘words.’ ______ on mRNA ___________ on tRNA ‘U’ (uracil) replaces ‘T’ in RNA This is the genetic code.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
