<span>The answer is carbon. Organic chemistry is the chemistry of carbon and hydrogen. The proteins, made of aminoacis are fundamental are the base of the chemical compounds and reactions that occur in the living organisms. Proteins are long chains of aminoacids. Aminoacids are made of carbon, hydrogen and oxygen. Carbon is the element that permits to build the long molecules thanks to its ability to form several (up to four) bonds with many elements, including other atoms of carbon. Is this ability to have multiple single bonds, or double and triple bonds what confer carbon the possibility to build so many different compounds being considered a building block of living things.</span><span />
The process of DNA replication is ALWAYS started immediately to the left of the RNA because DNA polymerase is an enzyme that needs RNA primer. It is required the presence of a primase for this process.
<h3>DNA replication and primase</h3>
DNA replication is always initiated by a specific RNA polymerase referred to as primase.
Primase is an RNA polymerase that generates a short RNA oligonucleotide known as primer, which is complementary to the DNA strand.
Subsequently, DNA replication is started immediately to the left of this RNA primer where DNA polymerase adds nucleotides to the growing DNA strand.
In conclusion, the correct (and missing) statement here is 'the process of DNA replication is ALWAYS started immediately to the left of the RNA because DNA polymerase is an enzyme that needs RNA primer'.

B, ligand-gated ion coupled receptor signaling
The radical in this question is OH.
The reason this will be a radical, is that the definition of a radical is the presence of an unpaired electron. This causes the radical to be unstable, desperately wanting to do something with the free electron that it has.
Oxygen has a charge of 2-, and Hydrogen has a charge of +1. When you pair them, you end up with a net charge of 1-, which is the presence of that unpaired electron. It will usually be written as:
