Why only four nucleic acids are used for DNA in virtually all life forms out of the thousands of nucleic acids known to chemists is evidence of the common ancient origin of all life forms.
Homework Answers
When we look at the DNA with 4 nucleotide & the DNA with 2 nucleotide, similar bit rates exists in both. But, the 4 nucleotide is two times better at bit packing. In the question of why four nucleic acids are used for DNA, it is because the DNA with 4 nucleotide system has speedy bit rate compared to any other system that make use of more nucleotides.
hope the answer helps.

5. Suppose we discovered a form of life like our own which utilized 20 amino acids, but had 6 nitrogeneous bases instead of the 4 our life uses. What would be the minimum length (i.e., number of base-pairs) of a codon which could represent all 20 currently used amino acids? 6. What evidence exists to support the idea that an ancestor of all present-day living organisms had a simpler genetic code in which the length of a codon was 2...
