Document Summary
Lecture 3 - september 29, 2016 - week 1. Pascal gagneux - guest lecturer: molecules of life. Dna contains life but is not living things. Need proteins, lipids, glycans: molecules of life in context. Dna segments in egg, sperm, every cell of body. Sperm - provides either x or y chromosome. 100 x 106 sperm enter, but only 100s make it to oviduct. Neutrophils have activated immune cells to attack sperm cells. Humans and gorillas are single partner mammals and have less sperm force. Cats and chimpanzees are multiple partner mammals and have strong sperm force. Implies that multiple partner needs to reproduce. Dna wrapped around histones chromosomes euchromatin nucleosomes chromatin. Chimpanzees have 1 less chromosomes than humans. 1 chromosome separated into 2 for humans. 22,000 protein-coding genes make 2% of total dna. Non-human primates live in tropical areas only. Hobbies - yoga, beekeeping: mammals and lactation. Supermammals - nurse young for very long time.
