Genetic information determines structure
... What is the difference between the 3’ and 5’ ends and how is this used in the genetic code? Explain what is meant by the phrase “the genetic code is redundant but never ambiguous”. What is meant by the phrase “the genetic code is universal”. Why is this important to biologist? Describe the process o ...
