Living things are based on a universal genetic code.
Explanation:
DNA, also known as deoxyribonucleic acid is a nucleic acid responsible for storing genetic information in living cells. The genetic code refers to the series of nucleotides that are expressed into a protein molecule. It comprises of all the codons (group of three nucleotides) in an organism.
All living organisms are said to contain a nearly universal genetic code because the same genetic code is found in almost all living organisms. For example, AUG codon corresponds Methionine amino acid in almost all organisms.
