Answer
Prokaryotic cells reproduce primarily through binary fission, and they can share genes through mechanisms such as transformation, transduction, and conjugation.
Solution
a
Binary Fission: Prokaryotic cells reproduce asexually through a process called binary fission. In this process, the DNA of the cell is replicated, and the cell divides into two genetically identical daughter cells
b
Transformation: This is a process where a prokaryotic cell takes up foreign DNA from its environment. This DNA can be integrated into the cell's genome, leading to genetic variation
c
Transduction: In this mechanism, bacteriophages (viruses that infect bacteria) transfer genetic material from one bacterium to another. This can result in the incorporation of new genes into the recipient cell's genome
d
Conjugation: This involves the direct transfer of DNA from one prokaryotic cell to another through a structure called a pilus. The donor cell transfers a plasmid (a small, circular piece of DNA) to the recipient cell, which can lead to genetic variation
Key Concept
Binary fission and gene transfer mechanisms in prokaryotes
Explanation
Prokaryotic cells reproduce through binary fission, a simple and efficient process. They can also share genes through transformation, transduction, and conjugation, which contribute to genetic diversity and adaptation.
