Why is DNA called a macromolecule by scientists? A.)because the nucleotide bases in DNA contain nitrogen atoms which make it lar
ge B.)because DNA is a massive polymer that contains many different parts C.)because DNA is made of one large, complex molecule of sugar D.)because purines and pyrimidines connect in DNA to make it a large molecule
B.)because DNA is a massive polymer that contains many different parts
Explanation:
DNA is also called Deoxyribonucleic acid and it is important in knowing the genetic composition of organisms. The DNA comprises of phosphate, a sugar called deoxyribose, and four nitrogenous base which are adenine, guanine, cytosine, and thymine.
These constituents named above form a long chain which could be in millions and billions. This is why it is regarded to as a macromolecule because it is a massive polymer that contains many different parts .
The nucleus of a eukaryotic cell directs the cell’s activities and stores DNA. not only does the membrane let molecules into the cell, but it also lets wastes suck as carbon dioxide out of the cell
