BIO 161 Chapter Notes - Chapter 15-16,18-19: Dna Replication, Start Codon, Aminoacyl-Trna
Document Summary
Objectives: write the central dogma of biology. Label the 5" and 3" ends of the dna and rna molecule. Also, label the template strand, the complimentary strand and rna polymerase. How does rna polymerase know where to initiate transcription? (promoter: how does secondary structure form in an rna molecule (base pair). Rna 2 structure in the termination of transcription (hairpin). In eukaryotes, how does a primary transcript differ from a mature mrna? (exon, intron, splicing, polya tail, 5" cap)* If given an mrna molecule, use the universal genetic code to determine the primary structure of the protein encoded by that mrna. 5" cgg aug guu cca gcg ugu aaa uag acg-3": distinguish between the roles of mrna, rrna, trna (information, enzymatic, amino acid, describe the role of trnas in translation. Describe the role of aminoacyl trna synthase in translation: draw a simple diagram of a ribosome (both subunits) interacting with an mrna.
