Suppose a new form of dna polymerase iii is discovered that does not require a primer to begin synthesis of a new strand. all other properties of the enzyme remain unchanged. if this new enzyme were to be expressed in the same organism that normally expresses dna polymerase iii, what would no longer be necessary to completely replicate all of the cellular dna? a. dna polymerase ib. telomerasec. dna ligased. dna helicasee. single strand-binding protein

The correct answer will be option-A

Explanation:

DNA replication is the process of making replicas of the DNA from the parent DNA strands mediated by the replication enzymes and the ATP.

DNA polymerase is the enzyme which adds a nucleotide to the 3' end of the growing polypeptide chain thus synthesizing the DNA strand in 5' to 3' direction.DNA polymerase requires an RNA primer sequence and DNA polymerase I to add nucleotides.

Since in the given question, a new DNA polymerase III does not require RNA primer which helps in the synthesis of the Okazaki fragments or the lagging strand, therefore, the cell will also no longer require DNA polymerase I as DNA polymerase I fill the gaps between the Okazaki frangments.

Thus, option-A is the correct answer.

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

                  5- inversion
