1. What does it mean when scientists say that living organisms share a universal genetic code?

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

3. 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?

4. How might similarities and differences in genetic codes, or the proteins built as a result of these codes, be used to determine how closely related different species are?

Answer 1 Scientists say that living organisms share a universal genetic code this means that the same genetic code that is used in humans is also used in all other types of organisms as well uses the same system of triplet nucleotide bases (codons) to code for a single amino acid when building a polypeptide..
