Adenine: Adenine is one of the four nitrogenous bases that make up the building blocks of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). Adenine pairs with thymine in DNA, and with uracil in RNA.

Nuclease: Nuclease is an enzyme that breaks down nucleic acids (DNA and RNA) into smaller nucleotides. There are different types of nucleases, such as endonucleases, which cleave nucleic acids at specific sites, and exonucleases, which remove nucleotides from the ends of nucleic acid strands.

PCR: PCR (polymerase chain reaction) is a laboratory technique used to amplify a specific DNA sequence. The process involves cycles of heating and cooling a reaction mixture containing DNA primers, nucleotides, and a DNA polymerase enzyme, which produces copies of the target DNA sequence. PCR is commonly used in research, medical diagnostics, and forensic analysis.
