Question

Which phrase best describes a true comment about the genetic code in DNA? Group of answer choices exactly the same in all organisms composed of five different nucleotides contains start and stop codons as instructions ambiguous, with different meanings in different kingdoms

Answer 1

Answer:

Exactly the same in all organisms.

Explanation:

All living organisms store their genetic information as DNA. The way in which the information is encoded is referred to as the GENETIC CODE. The genetic code comprises of all three nucleotides called CODON that encodea an amino acid in all organisms.

The genetic code is said to be UNIVERSAL i.e. the same genetic code is used by all known living organisms, as a codon does not specify another amino acid in another organism. It is universal in all organisms that AUG codon specifies Methionine. This universality of the genetic code further helps to show the shared ancestry between all organism.
