The correct statements that apply when describing the genetic code as universal are:
1. Most organisms use the same nucleotides in their RNA.
2. Most organisms use the same nucleotides in their DNA.
### Explanation:
The term “universal genetic code” refers to the idea that all known living organisms use the same basic set of nucleotides (A, T, C, G in DNA and A, U, C, G in RNA) for coding genetic information. While the sequences of these nucleotides may vary between species, the same nucleotides are employed across diverse life forms, allowing for fundamental similarities in the genetic code. This universality indicates a common evolutionary origin among all organisms.
