A form and Z form of double stranded DNA differ in the handedness of their helices, nucleotide sequences, and configuration of base to sugar. Based on these properties, which one of the following statements defines a correct combination for A and Z forms of DNA?
- 1Left handed double helix and syn-configuration for base to sugar arrangement in the A form DNA and right handed double helix and anti-configuration for the base to sugar arrangement for the Z form DNA.
- 2Left handed double helix and anti-configuration for base to sugar arrangement in the A form DNA and right handed double helix and syn-configuration for base to sugar arrangement in the Z form DNA.
- 3Right handed double helix and syn-configuration for the base to sugar arrangement in A DNA; and left handed double helix with alternating A and G sequence (as a general pattern), and anti-configurations for base to sugar arrangement in the Z DNA.
- 4Right handed double helix and anti-configuration for the base to sugar arrangement in A DNA; and left handed double helix with alternating sequence of G and C (as a general pattern), and alternating syn- and anti-configurations for the base to sugar arrangement in the Z DNA.✓
Correct answer
Right handed double helix and anti-configuration for the base to sugar arrangement in A DNA; and left handed double helix with alternating sequence of G and C (as a general pattern), and alternating syn- and anti-configurations for the base to sugar arrangement in the Z DNA.
