Biology 1002B Lecture Notes - Lecture 13: Start Codon, Transfer Rna, Nuclear Membrane
Document Summary
All the proteins in blue, are coded by genes that are no longer in the chloroplast. Chloroplasts genome is typically prokaryotic, environment inside the organelle. Genes on that genome are transcribed and translated in the chloroplasts. **theme: how to eukaryotes and prokaryotes do things differently. Everything alive uses dna, and uses similar gene expression. How does cell get information out of dna? mrna: can pair with itself giving it a secondary and tertiary structure that contains information. Riboswitch: influences translation of the mrna. Mrna+ mrna trna+ trna ribosomal rna (orange) base pairs with itself and is catalytic: catalytic properties leis in the rna not in the protein. Many genes code for rna, and rna doesn"t get translated, its rna. Green part is regulatory part, attract attention of rna polymerase. Rna polymerase binds onto promoters and it starts___ with the genes. Every polymerase reads the template 3" to 5". Once it gets promoted, it creates its ran polymer.
