Solution

The correct statement is: "Before division, the chromosome and plasmids are replicated."

Here's why:

Cell division is a process that requires the replication of the cell's genetic material so that each new cell receives a complete set of genetic instructions. This genetic material is found in both the cell's chromosomes and its plasmids (if any).

  1. Chromosomes: These are the primary carriers of genetic information in all cells. They are made up of DNA and proteins. Before a cell divides, its chromosome is replicated to ensure that each new cell gets a complete set of genetic instructions.

  2. Plasmids: These are small, circular pieces of DNA that are found in bacteria and some yeasts. They carry genes that can benefit the survival of the organism, such as antibiotic resistance genes. Like chromosomes, plasmids are also replicated before cell division to ensure that they are passed on to each new cell.

Therefore, the statement "Before division, the chromosome and plasmids are replicated" is true. The other statements are false because they suggest that either no DNA is replicated before
