The RNA world hypothesis states that the earlier life-forms had relied only on RNA (Ribonucleic Acid) for the purpose of catalyzing the chemical reactions, and storing the genetic information. This hypothesis was proposed by Leslie Orgel, Carl Woese, and Francis Crick.
This hypothesis states that long before the living forms evolved to use DNA as the genetic storage material, the RNA molecules served the purpose of both storing the genetic information and carrying out catalysis, but because of its instability, DNA evolved.
Hence, the answer is RNA world hypothesis.
Answer:
A single gene form different isoforms of protein that result from the alternative splicing of pre-mRNA sequences. one gene many polypeptide hypothesis applies here very well. This whole process helps in proliferating informational diversity and functional capacity of a gene that'll ultimately he;p in gene regulation.
This alternative splicing of pre-mRNA also produces proteomic diversity that result in various development states as well as various disease conditions later.
Answer:
One Idea was the appreciation that the age of the Earth was much greater than had hitherto for been imagined.
