Question

What is meant by the description antiparallel regarding the two strands that make up the dna double helix?

Answer 1

(B) The 5' to 3' direction of one strand runs counter to the 5' to 3' direction of the other strand.

Step-by-step explanation:

Answer 2

It means that one strand of DNA is in 5'-3' orientation is complementary to other that is in 3'-5' orientation

Step-by-step explanation:

Two strands in DNA double helix are in opposite directions alongside each other and that is called antiparallel orientation.

The 5' end of nucleic acid refers to phosphoryl end (phosphate group) while 3' end refers to hydroxyl (OH) group.

The property of anti-parallelism is important for the process of DNA replication.
