Question
A3' ............ 5'B
C5’ ........... 3'D.
AB and CD represent two strands of a DNA molecule. When this molecule undergoes replication, forming a replication fork between A and C in the above.
  1. Name the templete strand for replication.
  2. Using which strand as the templete, will there be continuous synthesis of a complementary DNA strand
  3. Complementary to which strand will okazaki segments get synthesised, discontinuous synthesis occurs.
  4. What are templete strands and Okazaki pieces?
  5. In which direction is a new strand synthesised?

Answer

  1. AB and CD
  2. AB strand
  3. CD strand
  4. The strands which dictates the sequence of the new strand, is the templete strand. Okazaki pieces are short stretches of DNA synthesised in the 5' 3' direction on discontinuous strand.
  5. In 5' → 3' direction.
