The telomeres are regions of short tandem repeats that encode very few if any genes. Replication of the telomeres via telomerase and a DNA polymerase does not involve O. frags, and hence there is no end replication problem. An entirely different system from DNA replication is used to duplicated...
DNA replication occurs in the regions of the nucleus and forms new DNA strands. This process implies the synthesis of DNA from DNA. It requires a range of enzymes, each of which has a significant function. Answer and Explanatio...
Regarding the process of DNA replication in E. coli which of the following statements is WRONG? ()A.DNA replication is a semiconservative process.B.There is a unique site at which replication is initiated.C.DNA replication is unidirectional.D.The mech
Replication of DNA starts with the unwinding of the entire DNA molecule. Each original strand is a therefore atemplate from which a new strand is synthesized based on complementary base pairing by DNA polymerase. Thenew DNA consists of an old parent strand and a new daughter strand. This proce...
