Answer: All of these DNA replication is one of the fundamental processes of living cell in whichteo identical replicas of parental DNA are formed. The DNA replication synthesis occurs at oriC were unwinding of DNA occurs leading to initiation of replication with the help of dna A protein whose concentration determines the process of replication and the DNA synthesis is done by DNA polymerase enzyme which needs a primer for adding nucleotides.
DnaA is a protein that activates initiation of DNA replication in bacteria. It is a replication initiation factor which promotes the unwinding of DNA at oriC. The onset of the initiation phase of DNA replication is determined by the concentration of DnaA.

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...

Fill in the Blank 1. DNA replication in E. coli begins at a 245 base pair sequence called • The initiation of DNA replication at this site begins with the binding of the protein, to multiple 9 base pair repeats regions. The association of these proteins generate superhelical tension which unwinds the 13 bp repeat region called the . The next step of initiation involves the loading of the protein (a helicase) onto the 13 bp repeat region by another...
