The building block of DNA is called the nucleotide, which is composed of a nitrogenous base (adenine, guanine, cytosine, or thymine), a five-carbon sugar (deoxyribose in DNA), â¦ and one to three phosphate groups.he phosphate is the same in DNA and RNA, but the sugar can be a ribose (for RNA) or a deoxyribose (for DNA). The latter is a ribose without  de-  one oxygen  -oxy- . There are four available nitrogenous bases in a DNA's nucleotides: adenine, thymine, guanine, and cytosine.

A local anesthetic (LA) is a medication that causes reversible absence of pain sensation, although other senses are often affected, as well. Also, when it is used on specific nerve pathways (local anesthetic nerve block), paralysis (loss of muscle power) also can be achieved. Clinical LAs belong to one of two classes: aminoamide and aminoester local anesthetics. Synthetic LAs are structurally related to cocaine.
