Read the sentence and answer the questions The process of replication requires a set of catalyst (enzymes). The main enzyme is referred to as DNA dependent DNA Polymerase. E.Coli that has only 4.6x106 bp (compare it with human whose diploid content is 6.6x106 bp), completes the process of replication within 18 minutes, that means the average rate of polymerisation has to be approximately 2000 bp per second these polymerase also have catalyse the reaction with high degree of accuracy. Deoxyribonucleoside triphophates serve dual purposes. In addition to DNA dependent DNA polymerases, many additional enzymes are required to complete the process of |
In E. Coli the main enzyme required to catalyze the polymerisation of deoxynucleotide is __________ |
DNA- Dependent DNA Polymerase DNA- Dependent RNA Polymerase RNA- Dependent DNA Polymerase RNA- Dependent RNA Polymerase |
DNA- Dependent DNA Polymerase |
The correct answer is Option (1) -DNA- Dependent DNA Polymerase In living cells, such as E. coli, the process of replication requires a set of catalysts (enzymes). The main enzyme is referred to as DNA-dependent DNA polymerase, since it uses a DNA template to catalyse the polymerisation of deoxynucleotides. These enzymes are highly efficient enzymes as they have to catalyse polymerisation of a large number of nucleotides in a very short time. |
