Answer 1

Living things are based on a universal genetic code.

Step-by-step 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.

Therefore, a blueprint of life called DNA is traceable to the fact that Living things are based on a universal genetic code.
