Premium DNA Molecular biology Gene expression
I had my first glimpse at molecular biology then. But that brief introduction to molecular biology was enough to compel me to the idea that I want to spend my whole life working and conducting research on it. That passion and zeal brought me to where right now I am. I have successfully completed my masters from the Department of Genetic Engineering and Biotechnology‚ University of Dhaka. I want to note that very few universities offer courses related to molecular biology here in Bangladesh but University

Fractionated on a CsCl2 gradient b) Precipitated with ethanol c) Poured over a resin column that specifically binds DNA B. Cutting DNA 1. DNA can be cut into large fragments by mechanical shearing. 2. Restriction enzymes are the scissors of molecular genetics. Restriction enzymes (RE) are endonucleases that will recognize specific nucleotide sequences in the DNA and break the DNA chain at

dawn of efflorescence in molecular biology‚ which provides an excellent basis for application of modern physics‚ biochemistry and computational techniques. Revelations of molecular structure become extremely crucial‚ as they provide insights into the way molecules work. My interest in the role of biomolecular structure in information processing and signal transduction pathways in the cell has developed during the last two years‚ while I have been a student of Molecular Biophysics sub-department

MOLECULAR FARMING INTRODUCTION Biotechnology in agriculture has two categories: 1. “Improvements” to existing livestock and crops‚ and 2. Development of entirely new uses for both animals and plants (biopharming). “Improvements"‚ include ‘input traits’ such as crops with extra resistance to insect attack‚ improved weed control‚ increase the plants tolerance to cold‚ drought and other environmental factor. Ex "Roundup ready" soya‚ "Starlite" corn‚ or "Frost-tolerant" tomatoes. WHY PLANTS

What would you expect to happen if you added ddCTP (shown in a) to a DNA synthesis reaction in vitro in large excess over the concentration of deoxycytidine triphosphate (dCTP)? How will this affect the pattern of bands on the sequencing gel? The ddCTP lacks the OH‚ which is required for elongation

Lab Report #1 Introduction A cell’s plasma membrane is known to be selectively permeable. This implies that the membrane is selective on what substances can pass in and out of the cell. There are two methods of transport that occur through the plasma membrane. One method of transport is called active process which uses ATP energy to transport substances through the membrane. The other method is called passive process which does not require the use of ATP energy. During passive processes

MOLECULAR DETECTION OF FUNGAL DISEASES INTRODUCTION With the rise of many new diseases caused due to viruses‚ bacteria and fungi; it is essential for the rapid detection of such diseases. The severity of such diseases can be reduced by its rapid detection carried out by different methods. The conventional methods may include the idea of just identifying the disease symptoms‚ identification of these pathogens in the laboratory by different morphological and biochemical tests‚ etc [1]. The conventional
