 Chromosomes Chromosome, the microscopic threadlike part of the cell that carries hereditary information in the form of genes. A defining feature of any chromosome is its compactness. For instance, the 46 chromosomes found in human cells have a combined length of 200 nm (1 nm = 10− 9 metre); if the chromosomes were … Read more Chromosomes

 Reflex action In the body of an animal two types of activities take place: voluntary and involuntary. Voluntary action happens according to the will of the individual while there is not any control of will over involuntary action. Involuntary action may again be divided into two categories. The action of first category is … Read more Reflex Action

 Ray optics Nature of light Light is a transverse, electromagnetic wave that can be seen by humans. The wave nature of light was first illustrated through experiments on diffraction and interference. Like all electromagnetic waves, light can travel through a vacuum. The transverse nature of light can be demonstrated through polarization. Light is … Read more Light

 Transgenic Plants Transgenic plants are plants that have been genetically modified by inserting genes directly into a single plant cell. Transgenic crop plants modified for improved flavor, pest resistance, or some other useful property are being used increasingly.   Transgenic plants are unique in that they develop from only one plant cell. In … Read more Transgenic Plants

The peripheral nervous system (PNS) consists of all neurons that exist outside the brain and spinal cord. This includes long nerve fibers containing bundles of axons as well as ganglia made of neural cell bodies. The peripheral nervous system connects the central nervous system (CNS) made of the brain and spinal cord to various parts … Read more DMPQ- Explain the importance of Peripheral nervous system

 Efforts of government in promoting biotechnology in the country DBT and Biotech parks The remarkable march of India into the world of biosciences and technological advances began in 1986. That year, government of india accepted the vision that unless India created a separate Department for Biotechnology, within the Ministry of Science and Technology, … Read more Efforts Of Government In Promoting Biotechnology In The Country

 Immunodiagnosis techniques Immunodiagnostics is a diagnostic methodology that uses an antigen-antibody reaction as their primary means of detection. The concept of using immunology as a diagnostic tool was introduced in 1960 as a test for serum insulin. A second test was developed in 1970 as a test for thyroxine in the 1970s. It … Read more Immunodiagnosis Techniques
