BIO152H5 Lecture Notes - Lecture 10: Messenger Rna, Nuclear Membrane, Central Dogma Of Molecular Biology
Document Summary
Midterm prep sessions: sunday oct 20th 5pm 6:30pm, monday oct 21st 6:30pm 8pm. This information content of genes is in the form of specific sequences of nucleotides. The dna inherited by an organism leads to specific traits by dictating the synthesis of proteins. Rna is the bridge between genes and the proteins for which they code. Transcription is the synthesis of rna using information in dna. Translation is the synthesis of a polypeptide, using information contained in the mrna. In prokaryotes, translation of mrna can begin before transcription has finished. In eukaryotic cells, the nuclear envelope separates transcription from translation. Eukaryotic rna transcripts are modified through rna processing to yield the finished mrna. A primary transcript is the initial rna transcript from any gene prior to processing. The central dogma is the concept that cells are governed by cellular chain of command. Overview: role of transcription and translation in flow of genetic information.
