Document Summary
Lecture 15 - 27/04/18 - gene expression i. Rna: single stranded, dna is transcribed into messenger rna (mrna) using base pairing, this mrna is translated into protein, the code is a triplet code - 3 nucleotides code for each amino acid. The rosetta stone: found in 1799, the top and middle texts are in ancient egyptioan using hieroglyphic or demotic. By using sythetic mrna"s and translating them invitro. A mouse has the gene coding for the firefly luciferase protein inserted into its dna. Since the genetic code is universal the mouse cells are able to express the firefly gene and produce functional fluorescent protein. Only 1 strand of the dna is used as the template for mrna synthesis. Transcription occurs in defined regions of dna - genes. The death cap mushroom: amanita phalloides induces death by kidney and liver failure in more than 50% of those who eat it.
