Answer:
The correct answer will be option-E
Explanation:
The structure of DNA revealed by Watson and Crick showed that Two strands of DNA are present in the intertwined state forming helix representing DNA as a double helix.
Each strand of DNA is made up of the monomer unit of DNA called nucleotide where each nucleotide binds to another nucleotide through weak covalent bond called phosphodiester bond.
The phosphodiester bond is formed between the 3’-OH group of one nucleotide to 5’ phosphate group of another nucleotide. In this way, the phosphate-sugar molecule forms the backbone of the DNA molecule.
Thus, option-E is the correct answer

Paenibaccilus polymyxa:
Aquaspirillum bengal: Helical
Explanation:
- Streptococcus pyogenes are gram positive, Round shaped, Anaerobic growth bacteria, Non-motile bacteria.
- Aquaspirillum bengal is helical in shape with its composition of deoxyribonucleic acid and cytosine. It is Gram negative and chemo-organotrophic. It is also motile with the help of flagella.
- Paenibacillus polymyxa is also known as Bacillus polymyxa which is capable of fixing nitrogen. It is found in soil, plant tissues and marine sediments. It has a major role in forest ecosystems and potential future applications as a biofertilizer and biocontrol agent in agriculture.
