Connecting Link – Archaeopteryx Archaeopteryx, the oldest-known fossil animal that is generally accepted as a bird. The eight or so known specimens date to approximately 150 million years ago during the Late Jurassic Period (161 million to 146 million years ago), and all were found in the Solnhofen Limestone Formation in Bavaria, Germany, starting in […]

Article On Pollution Anything added into the environment that results in producing harmful or poisonous effect on living things is called pollution. Pollution is the process that makes nature’s resources such as land, water, air or other parts of the environment unsafe or unsuitable to use. Pollution can be of many types: soil, air, water,

Kidney Stones Kidney stones are salt and minerals often made up of calcium or uric acid. They form inside the kidney and can travel to other parts of the urinary tract.Stones vary in size. Some are as small as the fraction of an inch or some are big. Others can grow to a few inches
The impact of climate change on the Himalayas The Himalayas is one of the youngest mountains chain in the world, lavished with biological diversity from Western to Eastern Himalayas. The mountain development and a panoramic view of the Himalayas have inspired humans for centuries, even spiritual inspiration. The Himalayan ecosystem is rapidly changing due to

Jhum Cultivation Jhum or Shifting cultivation is a primitive practice of cultivation in States of North Eastern Hill Region of India and people involved in such cultivation are called Jhumia. The practice involves clearing vegetative/forest cover on land/slopes of hills, drying and burning it before onset of monsoon and cropping on it thereafter. After harvest,
Atherosclerosis Atherosclerosis is tarts when the endothelium becomes damaged, allowing low-density lipoproteins (LDL – bad) cholesterol to accumulate in the artery wall. It’s the usual cause of heart attacks, strokes, and peripheral vascular disease — what together are called cardiovascular disease. Causes of atherosclerosis: Atherosclerosis begins with damage to the endothelium. That damage leads to
Purification tags/Protein tag Protein tags are peptide sequences genetically grafted onto a recombinant protein. Often these tags are removable by chemical agents or by enzymatic means, such as proteolysis or intein splicing. Tags are attached to proteins for various purposes. Affinity tags are appended to proteins so that they can be purified from their crude

Identification of recombinants You are approaching the end of your cloning workflow. The DNA fragment was ligated in the vector of choice and transformed into E. coli cells. The transformed cells were streaked across a culture plate resulting in a multitude of colonies overnight. How do you know that all of the steps have resulted

Analytical Chemistry Analytical chemistry studies and uses instruments and methods used to separate, identify, and quantify matter.[1] In practice separation, identification or quantification may constitute the entire analysis or be combined with another method. Separation isolates analytes. Qualitative analysis identifies analytes, while quantitative analysis determines the numerical amount or concentration. Analytical chemistry consists of classical,

Structure of Fullerene The icosahedral C60H60 cage was mentioned in 1965 as a possible topological structure. Eiji Osawa of Technology predicted the existence of C60 in 1970. He noticed that the structure of a corannulene molecule was a subset of an Association football shape, and he hypothesized that a full ball shape could also exist.
