Discussion of all aspects of biological molecules, biochemical processes and laboratory procedures in the field.
The Hypercycle theory explains this, it says that Nucleotids formed because of organic molecules in the primordial atmosphere combined to form small RNA molecules which catalysed, like ribozymes, the formation of more RNA.
So I guess it was the RNA because it can function as an enzyme on top of storing information.
For Prions, you forget one thing....it's "infectious" word...Prions are kind like an infectious proteins that synthesized by the cell itself...
Q: Why are chemists great for solving problems?
A: They have all the solutions.
what human cell? i don't know of anyone that old..
Viewed from the protein synthesis - DNA is a template for RNA, then RNA will initiate the protein synthesis
Viewed from the evolution - amino acid was created at the first time as a major component of organism (Oparin) but this still a theory since none able to prove on creating a organism from ancient components as mentioned by Oparin.
a human cell that old? where did they find it? and how did they decide it was human and how did they decide it was that old? Tell your professor to give a reference or people will probably think he is insane
My opinion is that the first wich appeared necessarily need to have at the same time an informative fonction and a catalic fonction, although RNA hasn't a high stability, it is for me the most serious candidate.
If the subjet interest you I advice you to read, a conceptually marvellous book: The Selfish Gene,2nd Ed. by Richard Dawkins
