|
All organisms have the same proteins.
|
|
|
All living things must have the same amount of DNA.
|
|
|
The codons in all organisms’ DNA code for the same amino acids.
|
|
|
The DNA blueprint varies based on how the nucleotides pair during replication.

Detailed explanation-1: -All organisms contain DNA and every organisms DNA is made of the same four nucleotides. The differences between organisms is simply based on the order of those nucleotides. Since al organisms have the same basic, universal structure for DNA, which of these must also be universal.
Detailed explanation-2: -Although each organism’s DNA is unique, all DNA is composed of the same nitrogen-based molecules. So how does DNA differ from organism to organism? It is simply the order in which these smaller molecules are arranged that differs among individuals.
Detailed explanation-3: -The genetic code is universal. All known living organisms use the same genetic code. This shows that all organisms share a common evolutionary history. The genetic code is unambiguous.
Detailed explanation-4: -Answer and Explanation: Yes, all organisms on the Earth use the same 5 nitrogenous bases. DNA contains adenine, thymine, guanine, and cytosine while RNA contains adenine, uracil, guanine, and cytosine.
Detailed explanation-5: -In short, DNA is a long molecule that contains each person’s unique genetic code. It holds the instructions for building the proteins essential for the body’s function. DNA instructions pass from parent to child, with roughly half of a child’s DNA originating from the father and half from the mother.
