Binary fission

Binary fission is a method of asexual reproduction commonly observed in prokaryotic organisms, such as bacteria. It is a relatively simple process in which a single parent cell divides into two identical daughter cells. Binary fission allows for rapid population growth in prokaryotes under favorable conditions.

Here are the key steps involved in binary fission:

  1. Replication: The genetic material, typically a single circular DNA molecule known as the bacterial chromosome, undergoes replication. This results in the formation of two identical copies of the genetic material within the parent cell.
  2. Elongation: The cell elongates and grows in size as the replicated DNA molecules move towards opposite ends of the cell. This elongation prepares the cell for division.
  3. Septum formation: A septum, or a partitioning membrane, begins to form across the center of the cell. The septum grows inward, gradually separating the two halves of the cell.
  4. Completion of division: The septum continues to grow until it completely separates the two daughter cells. At this stage, each daughter cell contains one copy of the replicated DNA and other cellular components necessary for independent functioning.
  5. Independent growth: The two daughter cells are now separate and can grow independently as individual organisms. They continue the metabolic activities and replicate their DNA to prepare for subsequent rounds of binary fission.

Binary fission is a rapid and efficient mode of reproduction that allows prokaryotes to quickly increase their population size. Due to the absence of complex nuclear division, it is relatively simpler compared to eukaryotic cell division processes like mitosis or meiosis.

It’s worth noting that while binary fission is commonly associated with prokaryotes, certain unicellular eukaryotic organisms, such as some protozoans, also undergo a similar form of asexual reproduction called binary division.

The AIIMS (All India Institute of Medical Sciences) entrance examination is a prestigious medical entrance exam in India. While I don’t have the specific syllabus for the AIIMS entrance examination, I can provide you with information on binary fission, which is a topic commonly covered in biology.

Binary fission is a form of asexual reproduction that occurs in single-celled organisms, such as bacteria and some protozoans. It is the most common method of reproduction in prokaryotes (organisms lacking a nucleus). During binary fission, a single organism divides into two identical daughter cells.

Here is a general outline of the process of binary fission:

  1. Replication: The genetic material, usually in the form of a single circular DNA molecule called the bacterial chromosome, replicates itself.
  2. Elongation: The cell elongates, and the two copies of the bacterial chromosome move apart, positioning themselves at opposite ends of the cell.
  3. Septum formation: A septum, or a cell wall, begins to form at the midsection of the cell. The septum grows inward, eventually dividing the cell into two separate compartments.
  4. Division: The septum continues to grow until it completely separates the two daughter cells. Each daughter cell receives one copy of the bacterial chromosome, as well as other cellular components necessary for independent survival.
  5. Completion: The two daughter cells are now fully separated and can grow independently, each functioning as a separate organism.

Binary fission is a rapid and efficient form of reproduction, allowing prokaryotic organisms to quickly increase their population size under favorable conditions.

It’s important to note that binary fission is specific to prokaryotes and differs from the process of mitosis, which is the form of cell division in eukaryotic organisms, including plants, animals, and fungi.

While this information provides an overview of binary fission, it’s advisable to consult the specific syllabus provided by AIIMS or refer to relevant textbooks and study materials to ensure comprehensive preparation for the AIIMS entrance examination.
