that paper is good and describes well how earlier organisms did in fact use amide bonds instead of sugar as the dna back bone but literally all eukaryotes and most modern prokaryotes use deoxyribose as a sugar back bone. that’s not what’s giving people dia
@amandahdez15 But please consider this exciting paper: https://t.co/AxzFiEE9OJ There is an alternative to ribose ...
@ifbacongrewont1 @jsanjosea But that's quite late in the genesis of life - many things happened before bacteria formed, and it seems possible that initial genetic code (before the 'RNA world') consisted of PNA without sugars! https://t.co/AxzFiEE9OJ
