Why are there up to four daughter strands being
synthesized at any one time during bacterial DNA replication?
Homework Answers
Ans. There is formation fo replication bubble at the time of replication of DNA by the action of helicase enzyme. In a replication bubble, synthesis of daughter DNA strands occur on both sense and antisense strands of DNA . DNA synthesis occurs in both directions from the centre of replication bubble. Hence, two strands on one side from the centre of replication bubble and two strands on the opposite side of bubble are used as template synthesizing four daughter strands simultaneously. Hence, four DNA daughter strands are synthesized simultaneously during DNA replication in bacteria.

DNA Replication. Sketch a replication fork of bacterial DNA in which one strand is being replicated discontinuously and the other is being replicated continuously. List six different enzyme activities associated with the replication process, identity the function of each activity, and show where each would be located on the replication fork. In addition, identify the following features on your sketch: DNA template, RNA primer, Okazaki fragments, and single-stranded DNA binding protein.

44. During DNA replication, the double helix is unwound, creating two single strands. One of these is called the strand, on which the progress of DNA Polymerase III is – 45. The other strand is called the strand, on which the synthesis is 16. During DNA replication, synthesis of a new sequence on the Leading Strand is continuous. Why is synthesis on the Lagging Strand discontinuous? 47. Generation of Okazaki fragments proceeds in three steps. Indicate which of the following...
