The primary information-carrying molecules in a cell are nucleic acids, and by controlling the production of proteins, they define the inherited traits of every living organism.
Deoxyribonucleic acid (DNA):
It consists of biological instructions, which make each and every species unique from the other.
It is made up of two linked strands.
Each strand has a backbone made of phosphate and alternating sugar.
Ribonucleic acid (RNA):
It is present in all living cells.
Its structures are similar to DNA, but most often it is single-stranded.
The strand has a backbone made of sugar ribose and alternating groups of phosphate.
