Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The genetic code is universal. This means ____
A
All living things share the same DNA, RNA, Amino Acids, and Proteins
B
All living things just have the same DNA
C
All living things have a nucleus
D
All living things build the same amino acid chains but use different DNA bases
Explanation: 

Detailed explanation-1: -The genetic code is universal. All known living organisms use the same genetic code. This shows that all organisms share a common evolutionary history.

Detailed explanation-2: -Is the code universal? No. Although most organisms have the same genetic code, researchers began to discover exceptions to the ‘universal’ code in 1979, and today we know of more than 15 alternative codes; each has just a few differences from the standard code, indicating common ancestry from this code.

Detailed explanation-3: -The genetic code is nearly universal, and the arrangement of the codons in the standard codon table is highly non-random.
