Document Summary
Base pairing is relevant in the secondary structures of mrna. Riboswitch in mrna can control gene expression and translation. Mrna contains information for controlling proteins, but it also contains information that controls the production of proteins. The anticodon on one end and the amino acid attached to the 3" end come together and a secondary structure forms. Ribosomal rna bases pair with themselves and is catalytic. Rna in ribosomes is doing the job of making the peptide bonds. All rrna pair with themselves to form secondary structure. The gene for dna polymerase codes for its own (gene) replication. (codes for a protein that makes more of the gene, because dna polymerase adds base pairs) Chlamydomonas has dna in three distinct cellular compartments. Organelles have typically bacterial gene structure and expression (bacterial ribosomes that are distinct from nucleic ribosomes) Although the basic steps of gene expression are the same in bacteria and eukarya, there are distinctions (make a list).
