The solution would be classified as acidic.
pH <7 is an acid.
pH >7 is a base.
I think it was <span>Rosalind Franklin who discovered what DNA was made up of.
</span>James Watson and Francis Crick discovered the double helix shape of DNA and also created a 3d model of it, so it's not B nor C.
To my understanding (you should double check) the answer is D
Genetic engineering often means insertion of a gene and
harvest of the protein from huge numbers of bacterial cells.
<span>Hemoglobin, are only functional as an assembly of multiple
sub-units. The ability to efficiently harvest the protein of interest and purify
it away from all the other proteins normally produced by the host cell, is one
of the major limiting factors for the large scale production of genetically
engineered hemoglobin.</span>
<span>The first organisms were prokaryotes that could withstand these harsh conditions. </span>
Answer:
It's drum. Guitar too, I guess.
