DNA Replication During DNA replication in prokaryotes, synthesis begins on the circular chromosome always at the same place at the promoter randomly on the chromosome at any stretch of DNA that is high in AT pairs always at the same place at the promoter randomly on the chromosome at any stretch of DNA that is high in AT pairs ANSWER DOWNLOAD EXAMIANS APP
DNA Replication Which of the following statements on replication in E.coli is correct? It occurs in bidirectional manner Always uses T7 DNA polymerase when infected by T7 phage It occurs in a unidirectional manner Occurs only when λ phase has infected E. coli It occurs in bidirectional manner Always uses T7 DNA polymerase when infected by T7 phage It occurs in a unidirectional manner Occurs only when λ phase has infected E. coli ANSWER DOWNLOAD EXAMIANS APP
DNA Replication Proofreading activity to maintain the fidelity of DNA synthesis occurs after the synthesis has been completed requires the presence of an enzyme separate from the DNA polymerases is a function of the 3'-5' exonuclease activity of the DNA polymerases occurs in prokaryotes but not eukaryotes occurs after the synthesis has been completed requires the presence of an enzyme separate from the DNA polymerases is a function of the 3'-5' exonuclease activity of the DNA polymerases occurs in prokaryotes but not eukaryotes ANSWER DOWNLOAD EXAMIANS APP

DNA Replication The replication of chromosomes by eukaryotes occurs in a relatively short period of time because the eukaryotic replication machinery is 1000 times faster than the prokaryotes the eukaryotes have more amount of DNA for replication each chromosome contains multiple replicons eukaryotic DNA is always single stranded the eukaryotic replication machinery is 1000 times faster than the prokaryotes the eukaryotes have more amount of DNA for replication each chromosome contains multiple replicons eukaryotic DNA is always single stranded ANSWER DOWNLOAD EXAMIANS APP
