Document Summary
2 lines of evidence: mitochondria and chloroplast, circular genomes, mitochondria and chloroplast, kept a lot of their machinery. A carnivorous, single-celled eukaryote: modern day eukaryote engulfed prokaryote. Leca in the middle of the second tree: green plants and algae, fish - parasites, sar paramecium, amoeba, opisthosomata animals and fungi animals more related to fungi. How do we study all this diversity: 19th and early 20th century approach. Central dogma refined: dna trna, transporting amino acids for protein synthetsis, mrna intermediate between rna and protein trna kind of like an intermediate between dna and proteins rrna, structural purposes. Overview: definite polarity, chains are essentially linear, everything will always be put together in a defined way to get this polarity, amino acid end and carboxylic acid end in protein. 3 parts of nucleic acid: know how to number carbons on sugars, pentose sugar ribose, nitrogenous base -gcat, phosphate group mono,di,tri phosphates, take note of phosphate"s negative charges.
