Answer:
Cell will not replicate because of incomplete DNA replication.
Explanation:
DNA replication is crucial for reproduction/replication of any organism as it involves the duplication of genetic material. So if an organism is unable to perform proper DNA replication it would not be able to reproduce.
DNA polymerase is the enzyme that synthesize the new DNA strand in DNA replication. DNA polymerase can synthesize a strand only in 5'→3' direction. Both of the strands of DNA molecules are opposite in direction. So one strand is synthesized continuously called as leading strand while the other strand is synthesized in form of okazaki fragments called as lagging strand.
The okazaki fragments are joined together by the enzyme ligase. So if Ligase enzyme is absent in bacteria it would not be able to synthesize the lagging strand of DNA and thus could not be able to produce a replica of DNA. And if there is No replication of DNA then No replication of cell would occur.
Answer:
the fourth one
Explanation:
since if it is a different way then it becomes something else
Its integral to the recombination and the genetic diversity from sexual reproduction on which natural selection can act upon. The recombination that occurs in meiosis plays an important role in the repair of genetic defects in Germ line cells.
B. It is a form of passive transport.
