1.	Observe the diagram and answer the questions:(a) What is the difference in the replication processes in A strand and B strand? (b) What is the role of DNA ligase in the replication process in B strand? (c) What is meant by Replication fork?
Answer» (a) In A, replication is continuous and form leading strand but in B replication is discontinuous and form lagging strand. (b) In B, short stretch of Okazaki fragments are connected with the help of DNA ligase and form continuous strand (c) The replication occur within a small opening of the DNA helix, referred to as replication fork. It appears as Y shaped forked structure.
