According to Watson and Crick model of DNA
1 DNA exists as a double helix
2 The two strands of polynucleotide are antiparallel to each other
3 The backbone is formed by sugar and nitrogen base
4 Both 1 and 2
Explanation:
Both options 1 and 2 are correct with respect to the structure of DNA elucidated by Watson and Crick. Option(3) is incorrect and can be corrected as The backbone of DNA is formed by the sugar phosphate sugar chain.
