PATHOLOGY

Detailed explanation-1: -Copying of DNA by replication enzymes begins at a spot on the chromosome called the origin of replication. The origin is the first part of the DNA to be copied. As replication continues, the two origins move towards opposite ends of the cell, pulling the rest of the chromosome along with them.

Detailed explanation-2: -Hence, the first step of binary fission is the duplication or replication of the parent cell’s genetic material (DNA).

Detailed explanation-3: -Binary Fission occurs without any spindle apparatus formation in the cell. In this process, the single DNA molecule begins replication and then attaches each copy to various parts of the cell membrane.

Detailed explanation-4: -In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.
