The characteristic feature of DNA double helix is- (A) Complementary & antiparalled (B) Always circular (C) Parallel (D) All of these |
|
Answer» Correct Answer is: (A) Complementary & antiparalled The DNA double helix is anti-parallel, which means that the 5' end of one strand is paired with the 3' end of its complementary strand (and vice versa). Nucleotides are linked to each other by their phosphate groups, which bind the 3' end of one sugar to the 5' end of the next sugar. |
