Nucleotides are the fundamental molecules that combine in series to form RNA .... RNA is made of long stretches of specific nucleotides arranged so that their sequence of bases carries information. The RNA world hypothesis holds that in the primordial soup/primordial sandwich, there existed free-floating nucleotides. These nucleotides regularly formed bonds with one another, which often broke because the change in energy was so low. However, certain sequences of base pairs have catalytic properties that lower the energy of their chain being created, causing them to stay together for longer periods of time. As each chain grew longer, it attracted more matching nucleotides faster, causing chains to now form faster than they were breaking down.
These chains are proposed as the first, primitive forms of life.
The RNA World hypothesis is supported by RNA's ability to store, transmit, and duplicate genetic information, as DNA does.
Just what i am looking for, thanks
The answer is:
1. The original necessary condition( ie: mechanism) for natural selection is the RNA( or pre-RNA).
2. RNA come to be what it is by the chaining of many Nucleotides where each Nucleotides interact according to the rules of chemistry.
Does anyone have anything to add to 1 and 2?
