Gregor Johan Mendel, the Father of Genetics, used Pisum sativum (garden pea) as the study material for his hybridization experiments. He studied the inheritance pattern of seven pairs of contrasting characters in Pisum sativum for deriving his conclusions. A combination of luck, scientific aptitude, foresight, mathematical background and most importantly […]

Interferons (INF): Definition, Antiviral Properties, Functions, Classification and Clinical Significance
Interferons are Glycoproteins with Antiviral Properties Interferons or INFs are low molecular weight glyco-proteins produced by certain eukaryotic cells in response to viral infections. They are cytokines with indirect or non-specific antiviral activities. Interferons stimulate the production of antiviral proteins in the cells which inhibit the synthesis of viral RNA […]

Solid State Fermentation: Examples, Advantages and Disadvantages
What is Solid State Fermentation (SSF)? In Solid State Fermentation, also called Solid Substrate Fermentation or SSF, the fermentation substrate or media will be in the solid state. Here the microorganisms are grown on a solid substratum in the absence or near absence of free water. The moisture content of […]

Philadelphia Chromosome and Oncogenic BCR ABL Gene Translocation in CML
Translocation is a Structural Aberration of Chromosome Translocation is a type of structural aberration of the chromosome where a segment of chromosome gets translocated to another chromosome. There may be two types of translocation based on the nature of the exchange. They are: (1). Homologous Translocation (2). Heterologous Translocation In […]

Graphical Representation of Data (Frequency Polygon, Frequency Curve, Ogive and Pie Diagram)
This post is the continuation of the Previous Post (Graphical Representation of Data Part 1). (3). Frequency Polygon Ø The Frequency Polygon is a curve representing a frequency distribution. Ø In frequency polygon, the mid values of each class are first obtained. Ø In a graph paper, the frequency of […]
