BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Nucleic acids are polymers that store, transmit, and express hereditary (genetic) information. This information is encoded in the sequences of monomers that make up nucleic acids. There are two types of nucleic acids: DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). DNA stores and transmits genetic information.

Detailed explanation-2: -In nature, just two closely related nucleic acids, DNA and RNA, function as repositories and carriers of genetic information.

Detailed explanation-3: -We now know that the DNA carries the hereditary information of the cell (Figure 4-2). In contrast, the protein components of chromosomes function largely to package and control the enormously long DNA molecules so that they fit inside cells and can easily be accessed by them.

Detailed explanation-4: -Nucleic acids store and transmit hereditary data. DNA and RNA represent the informational molecules of a cell.
