The two polynucleotide chains in DNA are:

Options

  1. Adiscontinuous
  2. Bantiparallel
  3. Csemiconservative
  4. Dparallel.

Correct answer

B. antiparallel

Step-by-step solution

Watson and Crick through their DNA model has shown that the two strands of DNA are antiparallel. One chain grows in 5^ 3^ direction and the other chain grows in the 3^ 5^ direction. Caution DNA is not semi conservative, but the replication process is.
