A 3' ______________ 5' B
C 5' _______________ 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.
(i) Name the template strands for replication.
(ii) Using which strand as the template, will there be continuous synthesis of a complementary DNA strand?
(iii) Complementary to which strand will Okazaki segments get synthesised and discontinuous synthesis will occur?
(iv) What are template strands and Okazaki pieces?
(v) In which direction is a new strand synthesized?

Explanation

(i)AB, CD (ii) AB (iii) CD
(iv) Template strands: Parental DNA strands complementary to which new strands of DNA are synthesized: Okazaki fragments are short segments of DNA synthesized on lagging strand
(v) 5'-3'
