Question

What are the steps of bacterial reproduction/binary fission? What are bacterial endospores? How do they form? How is an endospore different from a vegetative bacterium? From a fungal spore? Compare pure and mixed culture. Why is a pure culture needed to identify a pathogen? What is biofilm growth? What are the steps of biofilm formation? What is the architecture of a biofilm? Why are biofilms resistant to antibiotic treatment? Or to human immune response? What is metabolism? Catabolism? Anabolism? How does catabolism yield enerov?

Answer 1

1) Binary fission is the division of a fully developed bacterial cell into 2 daughter cells of equivalent size, following the replication of the genetic material.

The steps are :

The DNA of the organism uncoils & duplicates.

The DNA is moved to the different poles.

A fresh cell wall develops & starts to split the bacterium.

When the cell wall is fully developed, the bacterium is divided.

The daughter cells contains a densely coiled rod, ribosomes & plastids.

hope the answer helps.
