Question

Quizplus · Accepted Answer

The genetic code is considered universal because it is the same for all known living organisms on Earth, with only minor variations. This means that the same basic building blocks of DNA and RNA are used to code for the same amino acids, which are the building blocks of proteins, in all living things. While there are some variations and exceptions to this rule, the fact that the genetic code is so widely shared across different species is a strong testament to the common ancestry of all life on Earth.
