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
So, Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes.
It unwinds the DNA.
Explanation:
DNA is double stranded. Enzymes that are responsible for replication of DNA can only bind to a single strand of DNA.
So the answer is... A it breaks apart the bases.
Knowing the fact that around sixty percent of the human body is water, which consists of two hydrogen atoms and one oxygen atoms, and that other biomolecules like proteins also have oxygen atoms in their structure it's not a surprise that the percentage of oxygen in the human body mass is that high.
Even though there are two hydrogen atoms and only one oxygen atom in the water molecule, the oxygen atom has 16 times more mass than the hydrogen atom and therefore has a bigger contribution to the overall body mass.
