PCB 3063 Lecture Notes - Lecture 61: Restriction Enzyme, Myosin, Connective Tissue
Document Summary
The synthesis of proteins under the direction of mrna. Consists of a linear series of nucleotide triplets (codons) There are 20 different amino acids commonly found in proteins. Serve as biological catalysts, lowering the energy of activation in reactions and allowing cellular metabolism to proceed as body temperature. Proteins other than enzymes are critical components of cells and organisms. These include: hemoglobin: oxygen-binding molecule in red blood cells, insulin: pancreatic hormone, collagen: connective tissue molecule, actin & myosin: contractile muscle proteins. Used by bacteria to cut the dna of invading viruses. Could be used to cut any organism"s dna at specific nucleotide sequences, producing a reproducible set of fragments. The complete haploid dna content of a specific organism. Collections of clones that represent an organism"s genome. The use of recombinant dna technology and other molecular techniques to make products. The transfer of heritable traits across species using recombinant dna technology creates transgenic organisms.
