Question

Why dna strands are considered antiparallel

Answer 1

The nucleic acid sequences are complementary and parallel, but they go in opposite directions, hence the antiparalleldesignation. The antiparallel structure of DNA is important in DNA replication because it replicates the leading strand one way and the lagging strand the other way

Answer 2

DNA is double stranded, and the strands are antiparallel because they run in opposite directions.Each DNA molecule has two strands of. Each strand has , but the orientation of the sugar molecule is opposite in the two strands.

Both of the strands of DNA double helix can grow in 5' to 3' direction, but they grow in opposite directions due to opposite orientation of the sugar molecule in them.

The antiparallel orientation allows for the base pairs to compliment one another. Antiparallel DNA is also more structurally stable than parallel DNA.The antiparallel orientation of DNA has important implications for , as at theone strand allows steady replication, thereby known as leading strand while the other becomes lagging strand.
