What is Carbohydrates? Carbohydrates are bio-molecules composed of carbon, hydrogen, and oxygen atoms, generally with a hydrogen-oxygen ratio of 2:1. So, the simple formula is like Cm(H2O)n. Where, m is equal or not equal to n. For example glucose, C 6H 12O 6 or Cm(H2O)n, where, m=n=6. Carbohydrates are one of the three main macronutrients crucial for human body, like fats and proteins. They are major energy source and play a significant role in a number of physiological processes. Picture: Glucose-The simplest carbohydrates, Image by freepik.

DNA Replication DNA replication is the process by which a cell duplicates its DNA in preparation for cell division. The process involves a series of steps that are carried out by a variety of enzymes and proteins. Table of Contents Steps in DNA replication DNA replication is Semi conservative? Significance of DNA Replication conclusion References Steps in DNA replication Pic: Steps In DNA Replication, photo Credit:pixabay.com Initiation: The process of DNA replication begins at specific sites on the DNA molecule called origins of replication. At these sites, the double helix is unwound by an enzyme called helicase, which creates a replication fork. Priming: The next step is the priming of the DNA strands. The enzyme primase synthesizes short RNA primers that provide a starting point for DNA synthesis. Elongation: Leading and Lagging strands: DNA polymerase s

DNA Sequencing and it's Application in mordern day Table of Contents What is DNA? What is DNA sequencing? How is DNA sequencing done? Application Of DNA sequencing Conclusion What is DNA? Deoxyribonucleic acid (DNA) is a bio molecule with the characteristics of self-replicating, mutable, regulate of all biological function and carrier of hereditary information of a living cell. What is DNA sequencing? DNA sequencing is the process of determining the precise order of the nucleotides (building blocks) that make up a DNA molecule. DNA is made up of four nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G). By determining the order of these nucleotides, scientists can read the genetic code of an organism. The first DNA sequencing methods were developed in the 1970s and 1980s. These methods were slow, expensive, and labor-intensive, requiring weeks or m

Peroxixe Value : Peroxide value is a measure of the amount of peroxides in a substance, usually a fat or oil. Peroxides are formed when fats or oils are exposed to air or heat, and they can cause the fat or oil to go rancid. Therefore, measuring the peroxide value is important in determining the freshness and quality of a fat or oil. Table of Contents Methods of peroxide Value determination Materials and reagents Needed for determination Procedure of peroxide measurement Significance of peroxide Value In Summary Methods of peroxide Value determination Peroxide determination refers to the measurement or analysis of peroxides, which are compounds that contain an oxygen-oxygen single bond (O-O) and are often used as disinfectants, bleaching agents, and oxidizing agents in various industrial and chemical processes. There are several methods available for peroxide determination,

Standard Operating Procedure (SOP) for Menting Point Instrument: Ensure that the melting point machine is clean and free from any residual material from the previous use. Connect the machine to a suitable power source and ensure that it is properly grounded. Calibrate the machine according to the manufacturer's instructions before use. Prepare a sample of the substance to be tested. The sample should be dry, finely powdered, and uniform in size. Fill a small amount of the sample into a melting point capillary tube, making sure that the tube is not overfilled and that the sample is evenly distributed. Set the temperature range as per the manufacturer's instructions and turn on the heating source. Observe the sample as the temperature increases and record the temperature range in

Standard Operating Procedure (SOP) for Hanna pH Meter: Pic:Ph Meter Rinse the electrode with deionized water before using it. Avoid touching the bulb at the end of the electrode with your fingers, as oils from your skin can affect the accuracy of the pH reading. Immerse the electrode into the sample solution, making sure that it is fully submerged and not touching the sides or bottom of the container. Stir the solution gently with the electrode to ensure that the pH reading is consistent throughout the sample. Wait for the pH reading to stabilize on the meter display. This usually takes around 30 seconds. Record the pH reading on the data sheet or computer software. Rinse the electrode with deionized water after each measurement to prevent contamination and prolong the life of the electrode.

What is Fat? Fat is one of the essential nutrients for the human body. 60% of the brain is made up of fat. This fat helps in body heat production, brain development, production of various hormones, absorption of fat soluble vitamins (A, D, E, K) and maintaining good health of skin and other organs. Basically, fat acts as an insulator to maintain proper body temperature. Fats are sometimes classified in two areas: healthyfat that means good fat and bad fat. In this article, I am going to discuss about healthy fat. Pic: a women aware about healthy fat, photo Credit; freepik. OutLine Of the article What is healthy fat? Some examples of healthy fats.

Cell- The smallest unit that can live on its own and that makes up all living organisms and the tissues of the body: Robert Hooke (1635-1703) in 1665 made thin section of wood cork and observed them under a microscope. He found there numerous little boxes like bee hives. Then he remembered seeing such small rooms for the priests to stay in the monastery. From this, he named the cork’s little box as “cell”. The word cell is derived from the Latin word cellula, means little box. Pic: Cell, Photo Credit: freepik.

What is Plasmid? A plasmid is a small double stranded circular DNA molecule found in bacteria andsome other microorganism. Plasmids are extra-chromosomal DNA, that means the are physically separate from chromosomal DNA. Replication of chromosome in unrelated to bacterial chromosome replication. Pic: Plasmid, Photo Credit: freepik. Plasmids are used in recombinant DNA technology as a carrier of target gene. In nature, plasmids frequently carry genes that aid in the survival of the organism and provide selective advantage such as antibiotic resistance. Artificial plasmids are readily used as vectors in molecular cloning, aiding to operate the replication of recombinant DNA sequences within host organisms. By the process of transformation, plasmid may be uptake by a bacterial cell . Now-a- days synthetic plasmids are also found commercially over the e-commerce market.
