The first genetic material on earth was probably
a. dna molecules whose information was transcribed to rna and later translated in polypeptides
b. dna produced by reverse transcriptase from abiotically produced rna
c. oligopeptides located within protocells
d. self-replicating rna molecules

d. self-replicating RNA molecules

Explanation:

RNA molecules are single stranded, not included double stranded RNA structures from self folding, and DNA molecules are double stranded. It is thus believed that RNA molecules was the original genetic material and eventually DNA evolved from RNA and overtook RNA as the genetic material given DNA enhanced stability. Thus the answer has to be RNA.

if, i suppose that a bee stings me swinging my hand away from a bee. then that if, i persist patient when a bee or wasp areas on your surface to investigate a scent or to take h2o and i secreting heavily, the bug ultimately will move of its personal agreement. if i don't need to set for it to disappear, lightly and gently wipe it off with a part of the paper.
