The label A in the given image is pentose sugar, B is phosphate group, C is phosphate group, D is cytosine, E is adenine, and F is a nucleotide.
What is DNA?
Deoxyribonucleic acid is a polymer made up of two polynucleotide chains that tangle into one another to form a double helix that contains genetic instructions for the development, operating, growth, and procreation of all lifeforms and viruses. Nucleic acids include DNA and ribonucleic acid.
Nucleotides are strung together in 2 long strands to form a spiral known as a double helix.
The framework of the double helices is similar to that of a ladder, with the base pairs forming the rungs and the sugar and phosphate molecules forming the ladder's vertical sidepieces.
Thus, the label A is pentose sugar, B is phosphate group, C is phosphate group, D is cytosine, E is adenine, and F is a nucleotide.
