If one took DNA samples from two strangers on a street, the two DNA samples will be 99.9% the same (option C).
What is DNA?
DNA is the part of a living organism that carries or stores genetic information.
The DNA molecule is made up of four nucleotide bases namely;
- Adenine
- Guanine
- Cytosine
- Thymine
However, the DNA of every living organism is the same with the difference lying in the arrangement of the nucleotide sequence.
Therefore, if one took DNA samples from two strangers on a street, the two DNA samples will be 99.9% the same.
The 0.1% difference is attributed to the mutations that might have occured in the genome.
