Answer:
Nucleic acids are the organic materials present in all organisms in the form of DNA or RNA.
These nucleic acids are formed by the combination of nitrogenous bases, sugar molecules and phosphate groups that are linked by different bonds in a series of sequences.
Explanation:
“DNA is a group of molecules that is responsible for carrying and transmitting the hereditary materials or the genetic instructions from parents to offsprings.”
DNA is known as Deoxyribonucleic Acid. It is an organic compound that has a unique molecular structure. It is found in all prokaryotic cells and eukaryotic cells.
The four roles that DNA plays in the cell are:
(1) storage of information via the genetic code so that cellular processes can be initiated and maintained.
(2) the generation of genetic variation through mutation and recombination.
(3) The copying and replication of genetic information so that it can be passed onto daughter cells. It is this function that makes DNA the molecule of inheritance.
(4) gene expression. The transcription and translation of genetic material to produce proteins, enzymes and other gene products necessary for growth and life.
