DNA expresses the genetic code and the arrangement of that code determines the characteristics of different and diverse organisms. Which of the following
statements does NOT support the universality of DNA?

However, most non-canonical genetic codes are inferred from DNA sequence alone, or occasionally DNA sequences and corresponding tRNAs. Because the code governs the translation of nucleotide to amino acid sequences, a code can in principle only be confirmed when both the gene and protein sequences are known

Explanation :DNA is considered a universal genetic code because every known living organism has genes made of DNA. ... Every living organism uses that same system. Basically, every three pieces of DNA becomes one amino acid.

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
