Read the following text and answer the following questions on the basis of the same :
DNA, a long polymer of deoxyribonucleotide. Altmann and these substances to be acidic hence he named nucleic acid. The basic unit of DNA is a nucleotide which has three components—a nitrogenous base, a pentose sugar (deoxyribose) and a phosphate group. There are two types of nitrogenous bases in DNA, Purine and Pyrimidine. J. Watson and F. Crick proposed a double helix model for the structure of DNA. There are four types of DNA i.e., A, B, C, Z.
Which DNA form has the maximum number of base pairs per turn ?
  • a)
    A-DNA
  • b)
    B-DNA
  • c)
    C-DNA
  • d)

Explanation:

Maximum number of base pairs per turn in Z-DNA:
- Z-DNA is a left-handed double helical form of DNA.
- It has a zigzag structure which allows for the maximum number of base pairs per turn compared to other forms of DNA.
- Z-DNA contains approximately 12 base pairs per turn, making it the form with the highest number of base pairs per turn.

Other types of DNA:
- A-DNA is a right-handed double helix with around 11 base pairs per turn.
- B-DNA is the most common form of DNA found in cells and has approximately 10 base pairs per turn.
- C-DNA is a type of DNA with a left-handed helix and around 9 base pairs per turn.

Conclusion:
- In conclusion, Z-DNA has the maximum number of base pairs per turn compared to A-DNA, B-DNA, and C-DNA. This unique structure of Z-DNA allows for more interactions between the nitrogenous bases, contributing to its biological significance.
