BIOL303 Lecture Notes - Lecture 1: Syndactyly, Multicellular Organism, Base Pair
Document Summary
Most prokaryotic genes produce polycistronic mrna internal ribosome binding sites ribosomes 70s (50s + 30s) (translation and transcription happen at the same time), no introns. Most eukaryotic genes contain introns (except yeast), transcripts bind ribosome by 5" ribosomes 80s (60s + 40s) sexual reproduction through meiosis cytoskeleton mrna cap, do not produce polycistronic mrna. Average size protein in yeast is 466 aa = 53 kda. How many base pairs are there in a genome: there are approximately 3 million base pairs in a human genome. Budding yeast (saccharomyces cerevisiae) approximately 12mb, 6,300 genes. Fruit fly (drosophila melongaster) approximately 137 mb, 13,600 genes. C. elegans (a nematode) approximately 97 mb, 19,00 genes. Humans 3,200 mb (3. 2 gb), approximately 25,000 genes. Studies how a multicellular organism forms from a single cell and how that organism: Produces other single cells that subsequently propagate the species (germ line)
