What was the process of replication referred to as in the living cells like E. coli?
Options
- ADNA-neutral DNA polymerization
- BRNA-dependent DNA polymerization
- CDNA-independent DNA polymerization
- DDNA-dependent DNA polymerization
Correct answer
D. DNA-dependent DNA polymerization
Step-by-step solution
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 catalyze the polymerisation of deoxynucleotides. These enzymes are highly efficient enzymes as they have to catalyze polymerisation of a large number of nucleotides in a very short time. E. coli that has only 4.6 ×106 bp (compare it with humans whose diploid content is 6.6 × 109 bp), completes the process of replication w
