Oligonucleotides are used as both primers and probes. The repeated copying of a DNA segment between two known primer sequences, amplifying it exponentially. Also referred to as a polypeptide. The sequence of the amino acids, and thus the function of the protein, is determined by the sequence of the base pairs in the gene that encodes it. Proteins are essential to the structure, function, and regulation of the body.
Examples are hormones, enzymes, and antibodies.
There are many different enzymes that recognize different sequences. The several classes of RNA molecules play important roles in protein synthesis and other cell activities. This is a single-base pair difference between two individuals. Also referred to as RNA synthesis. Also referred to as protein synthesis.
