If I say let’s become familiar with the Asteraceae family, probably it will not be so effective but if I say that let’s become familiar with the family of sunflower and dahlia flower it will be better to understand. As we do in the case of identifying a person’s family …

It’s always helpful and extra-beneficial to check the background or history before learning a new subject matter. Why? Because this enrich us with some fundamental concepts behind the topic and enable us to understand how versatile ideas bloom and differentiate to shape a new body of knowledge. Isn’t that interesting!!! …

Before starting the detailed discussion first I simply answer the first arising question what is author citation? In a sense of Botany, every living being has a unique botanical name by which it is recognized (i.e.Mango=Mangifera indica, Jackfruit=Artocarpus heterophyllus), if it does not have any then it will have sooner …

The polymerase chain reaction, generally known as PCR, is used in almost every application of gene technology. It is a method for rapid production of a very large number of copies of a particular fragment of DNA. Virtually unlimited quantities of a length of DNA can be produced from the …

DNA Barcoding DNA barcoding is a method of species identification using a short section of DNA from a specific gene or genes. Everyone is familiar with industrial barcodes as unique identifiers for commercial products. Similar to these industrial barcodes, short gene segments – known as DNA barcodes – are unique …

What is marker? Marker may be defined as “Mark of identification”. In Biology three major types of markers are used: Morphological marker (also called “classical” or “visible” markers) which are phenotypic traits.

The steps in the biosystematic investigation are as follows A sampling of taxon and its population and cytological study of the chromosome of many populations within geographical races, species, and genera; differences in chromosome number, morphology, and behavior of meiosis indicated genetic differences. Determination of the ability of the different …
