Transcription and RNA Processing AP Biology 63

This section of the AP Biology curriculum focuses on the process of transcription and the RNA processing mechanisms that stabilize a pre-mRNA molecule, remove the introns, and ready the molecule for export from the nucleus and translation into a protein molecule. We’ll start by taking a look at how RNA polymerase functions to create a primary RNA transcript from a DNA molecule. Then, we’ll see the three types of RNA (including messenger RNA, transfer RNA, and ribosomal RNA) that work together to translate information from the nucleic acid language to the amino acid language. Finally, we’ll see how alterations to the RNA processing mechanisms can create alternative splicing - different versions of a protein, based on the exons and introns that are kept in the finalized mRNA molecule. • Resources related to this Video: • ● Overview: The same information, for those who prefer to read.
