BIOMOLECULES AND ENZYMES

Detailed explanation-1: -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). As shown in Figure 4, 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.

Detailed explanation-2: -The strands of a DNA double helix are said to be “antiparallel” because the have the same chemical structure, but are opposite in direction.

Detailed explanation-3: -antiparallel definition. A term used to describe the opposite orientations of the two strands of a DNA double helix; the 5’ end of one strand aligns with the 3’ end of the other strand.

Detailed explanation-4: -Antiparallel strands of a DNA molecule means that the phosphate groups at the start of two DNA strands are in opposite position (pole). The DNA molecule is composed of two strands held together by hydrogen bonds. A single strand is different at its two ends.
