Cardiovascular disease can affect both the heart and blood vessels and the most common sign is chest pain. It is the leading cause of death in the United States with it being responsible for one in every four deaths. Quitting smoking will improve the health of the heart and blood vessels as well as greatly reducing the risk of recurrent heat attack and cardiovascular death.
Answer:
C. 3´OH
Explanation:
DNA is a large molecule built up by linking together smaller molecules called nucleotides.
A nucleotide contains a phosphate group, a sugar (deoxyribose in the case of DNA) and a nitrogen base.
The <em>nucleotides are linked together by the binding of</em> the phosphate group on carbon 5 in the nucleotide that is added, and the oxygen of the hydroxyl group (-OH) on carbon 3 of the last nucleotide of the DNA chain.
These bonds are called phosphodiester bonds and their formation releases a molecule of H2O.
This reaction is catalyzed by an enzyme, DNA polymerase, that requires a free 3´ hydroxyl group (3´ OH in the growing chain) to add the new nucleotide.
I think it’s D but not 100% sure.
