Detailed explanation-1: -Nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.
Detailed explanation-2: -Nucleic acids are naturally occurring chemical compounds that serve as the primary information-carrying molecules in cells and make up the genetic material.
Detailed explanation-3: -Nucleic acids are long linear or circular macromolecules, either DNA or various types of RNA, that are composed of linked nucleotides. These molecules carry genetic information that directs all cellular functions.
Detailed explanation-4: -Nucleic acids are responsible for the transmission of inherent characters from parent to offspring. DNA fingerprinting is a method used by forensic experts to determine paternity. It is also used for the identification of criminals.
Detailed explanation-5: -The major function of nucleic acids is to store the genetic code of living organisms. DNA reserves genetic information and is responsible for maintaining the identity of species over the centuries.
