Introduction: DNA or deoxyribonucleic acid carries hereditary information from one generation to another. After several experiments, scientists have found evidence that claims that DNA is the hereditary material that passes on the genetic information from one generation to the next. DNA can be transferred through sexual or asexual reproduction. Proteins are products obtained from DNA after transcription and translation.
