Introduction The major components of the chromosomes are: must read: What are Chromosomes? : Its function, and Structure Proteins Histones Non-Histone proteins They are primarily acidic and as regulatory molecules considered more important than the histones. In simple words, we…
Definition The process of conversion of double stranded DNA molecule into two identical DNA molecules is known as DNA replication. DNA replication in prokaryotes is different from DNA replication in Eukaryotes. The double stranded DNA molecule is called a parental…
What are Chromosomes? Inside the nucleus, Chromosomes are the thread like structure of Nucleic acids (DNA and RNA) and proteins (Histones and non-histones) present in most living cells in the form of genes (unit of heredity) which contains all the…
History: Know the brief history of cell wall: In 1665, Robert Hook was the first scientist who observed and named the cell. In 1804, Karl Rudolph and J.H.F. see the cell had many cell walls which are independent. Also read:…

WHAT IS CELL BIOLOGY Cell biology is the branch of biology that deals with the study of cells. It is also termed “cytology.” Cell structure, function, and behavior all come under cell biology. CELL A cell is the…
Microbes are tiny living organisms that are an integral part of the environment. They are present freely, in the environment although their habitat is specific. Microbes can be beneficial as well as harmful, it mostly depends on their pathogenicity. To…
Principle of acid fast stain Most bacterial organisms can be stained with either a simple stain or a Gram stain, but the acid-fast method works much better for a few genera, especially those in the genus Mycobacterium. Since both M.…
When you are dealing with microbes in your lab, one thing that is always problematic is the growth of unwanted microorganisms. Contamination can cause trouble not only in hospitals or diagnostic labs but also in the food and pharmaceutical industries…
In nature, microbial populations are not separated by species but exist with a mixture of many different types of cells. In the laboratory, these populations can be separated to make pure cultures by different culturing techniques. These cultures only have…
