Document Summary
Had specific adaptations on molecular level for reducing heat loss. Can discover and extract dna from mammoth, found preserved in ice and freezing it in cold conditions helped control the breakdown, sequence small parts and sequence the genome with a computer. Some discussion to whether or not you could bring them back. Where would it live: de-extinction may be an actual thing. Looking at reconstructing one part of the mammoth. If you allow your appendages to cool, harder for oxygen to get off hemoglobin. Reconstructed hemoglobin from dna, creating mrna and then a functional protein. If you were to look at hemoglobin from mammoths and elephants, they wouldn"t be that similar. The mammoth ones would look similar to arctic or cold-adaptive animals. Measured if it was better at binding and releasing oxygen at colder temperatures. Set of mutations, probably favored through natural selection. These crocodile fish don"t have hemoglobin (for oxygen uptake and transfer, vital for most vertebrates)
