The process of binary fission begins with a single mother cell and ends with two daughter cells. Would you expect the mother and daughter cells to be genetically identical? Explain why or why not.
To review:
Whether mother and daughter cells are genetically identical when they areformed by binary fission.
Introduction:
The process of reproduction in which offspring are produced by a single parent or a single organism where there is no need forfusion of the gametes, is known as asexual reproduction. Asexual reproduction mainly takes place in single-cell organisms, such as algae, bacteria, and fungi.
Explanation of Solution
Binary fission is the method of asexual reproduction in prokaryotes, through which new organisms are produced, that are genetically identical to the parent organism.In the process of binary fission, the DNA (deoxyribonucleic acid) within the cell is replicated, the copies then slide to opposite terminals of the cell in an energy-dependent process.
The cell elongates and equatorial plane of the cell contracts, whichsegregates the cell’s plasma membrane, following which, new cells are generated which constitute exactly the same genetic material.Thus, daughter cells are generated from a single parent cell and have same genetic material as well as cell components, so, theyare genetically identical. However, they are identical when the mutations are not considered.
Therefore, it is concluded that mother and daughter cells are genetically identical when they are generated by binary fission because they shareidentical copies of genetic material from a mother cell, provided that the mutations did not take place during replication.
