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).
A Lifesaving Drug. Epinephrine pens, or EpiPens, can be lifesaving tools. The epinephrine (also called adrenaline) is a cardiac stimulant and is used for severe allergic reactions of all types, including food, drug, insect bites, and stings.Prescribed to those for whom the risk of anaphylactic shock due to allergic reaction is very high, it comes in the form of an auto-injector or âpenâ.he epinephrine (also called adrenaline) is a cardiac stimulant and is used for severe allergic reactions of all types, including food, drug, insect bites, and stings.
