The genetic code is the relationship between DNA base sequences and the amino acid sequence in proteins. The genetic code features include: 1  amino acids are encoded by three nucleotides. 2  it is non-overlapping. 3  it has no punctuation (alternatively, the stop codons could be viewed as a period or full stop.).
Norepinephrine, also called noradrenaline, is an organic chemical in the catecholamine family that functions in the human brain and body as a hormone and neurotransmitter.nside the brain norepinephrine functions as a neurotransmitter, and is controlled by a set of mechanisms common to all monoamine neurotransmitters. After synthesis, norepinephrine is transported from the cytosol into synaptic vesicles by the vesicular monoamine transporter (VMAT).
Norepinephrine is also made in the adrenal medulla where it synthesized from dopamine and is released into the blood as a hormone. Epinephrine is made from norepinephrine inside the adrenal medulla (the inner part of the adrenal gland, a small gland associated with the kidneys). Our adrenal medulla helps us to cope with physical and emotional stress. The synthesis of epinephrine increases during times of stress.
