Question

Part A Polynucleotides adopt primary, secondary, and tertiary structure. Which of these statements are true? 1. The major two forms of polynucleotide secondary structure helices are called A and B 2. The primary structure of nucleic acids refers to the sequence of nucleotides in the linear molecule. 3. Supercoiling is part of secondary structure. 4. The tertiary structure is the higher-order folding of elements of regular secondary structure. View Available Hint(s) All statements are true. 1 and 2 1, 2, and 4 2 and 4 Submit

Explanation / Answer

Opt4 is correct - 2 and 4

1. Two major forms of polynucleotide in secondary structure are alpha helix and beta pleated sheets not A and B

2. Primary structure is linear sequence of nucleotides

3. Supercoiling occurs in DNA not in he structures of he protein.

4.teritary structure is high order folding gives the 3D structure of the protein
