Question

How does a universal genetic code relate to the hypotheses about the origin of life on Earth?

Answer 1

The universality of the genetic code means that all living organisms are descended from one original organism, which is at least useful information. [ From a religious point of view, it could also be said that the creator god designed a successful genetic code and chose to use it universally. So, the genetic code does not actually prove or disprove evolution versus religion. But it proves the Theory of Evolution to be the best scientific explanation of life on earth. ]

Answer 2

awesome, but, my science teacher is and atheist so id rather not write something about god..

Answer 3

I got this off the internet all organisms on Earth have one genetic code (except
mitochondrias that probably changed it for some reasons). In fact,
universal genetic code is fundamental evidence that all organisms
(viruses, bacterias, eucariotes) evolved from one common ancestor,
because otherwise organisms should have different genetic codes.
Furthermore, according to hypothesis of RNA world, all modern organisms
came from one ancestor that was composed only from nucleic acids. This
ancestor had RNA as a carrier of genetic information, and used same
genetic code as now-living organisms

Answer 4

thank you sooooo much omg! <3

Answer 5

How are self-replicating molecules, such as RNA molecules in the “RNA World” hypothesis, essential to the most popular hypotheses about the origin of life on Earth? do you know that one too ? lol

Answer 6

Note: The RNA world hypothesis proposes that self-replicating ribonucleic acid (RNA) molecules were precursors to current life, which is based on deoxyribonucleic acid (DNA), RNA and proteins. [ RNA stores genetic information like DNA, and catalyzes chemical reactions like an enzyme protein. It may, therefore, have played a major step in the evolution of cellular life.[1] The RNA world would have eventually been replaced by the DNA, RNA and protein world of today, likely through an intermediate stage of RNP enzymes such as the ribosome and ribozymes, since proteins large enough to self-fold and have useful activities would only have come about after RNA was available to catalyze peptide ligation or amino acid polymerization.[2] DNA is thought to have taken over the role of data storage due to its increased stability, while proteins, through a greater variety of monomers (amino acids), replaced RNA's role in specialized biocatalysis. The RNA world hypothesis is supported by the observation that many of the most critical components of cells (those that evolve the slowest) are composed mostly or entirely of RNA. This would mean that the RNA in modern cells is an evolutionary remnant of the RNA world that preceded ours. Also, many critical cofactors (ATP, Acetyl-CoA, NADH, etc.) are either nucleotides or substances cleclearly related to them. ]

Answer 7

Most theories of the origin of life concider RNA molecules, which
possess ribozymes activity as a primary self-replicating molecules
that gave rise to the development of life on Earth. Results of the
study two hypothetical groups of ribozymes are the basis of modern
ideas about the origin of life. First of all, this is an RNA
replicase, constructed entirely of ribonucleotides. This assumption
seems particularly attractive,because the ancient RNA molecules could
store genetic information and have enzymatic activity necessary for
the reproduction of this information. This combination of properties
in the RNA molecule can explain how the catalytic functions performed
by modern protein molecules, as well as a function of storage and
transmission of genetic information occurred simultaneously and could
be present in a single precursor molecule ancestors of modern cells.
Theories of the origin of life which based on the original
participation of RNA molecules in the creation of self-replicating
systems found strong support in connection with the opening splicing
and ribozymes.
