Chemical evolution of amino acids and proteins ? Impossible !!
https://www.youtube.com/watch?v=1L1MfGrtk0A
The problem of getting nitrogen to make amino acids and DNA on early earth 2:41
The problem of getting all amino acids used in llife by origin of life experiments 4:20
The problem of selecting 20 amino acids prebiotically out of hundreds supposedly existing on early earth. 6:08
The problem of concentrating the amino acids used in life at one assembly site. 7:15
The problem of understanding why life uses 20 amino acids, and not more or less. 9:00
The problem of homochirality 12:23
The problem of amino acid synthesis regulation 13:43
The problem of peptide bonding of amino acids to form proteins 14:12
The problem of linking the right amino acid side sequence together 17:15
The problem of getting the right forces to stabilize proteins - essential for their correct folding 19:32
The problem of hierarchical structures of proteins 19:50
