ii. Structural motifs in many DNA binding proteins.
iii. Structures with high redox potential.
iv. Characteristic of palindromic stretches of unique DNA sequence​

Answer 1

Answer:

Because ;

Structural motifs in many DNA binding proteins.

Answer 2

Answer:

ii. Structural motifs in many DNA binding proteins.

Explanation:

because,

Functionally, these motifs carry out a wide variety of tasks within cells by providing stable structural scaffolds and driving critical binding interactions, especially among proteins, DNA, and RNA.
