What is hydroponics and how plants survive in soil less medium?

Introduction Hydroponics is a type of farming method that involves the cultivation of plants in a soilless environment. The word "hydroponics" comes from the Greek words "hydro," meaning water, and "ponos," meaning labor. Hydroponics involves growing plants in a nutrient-rich solution rather than in soil, allowing for optimal growth and plant development. In hydroponic farming, plants are typically grown in a controlled environment, where the grower has complete control over factors such as temperature, humidity, and lighting. This allows for optimal growing conditions, resulting in higher yields and faster plant growth. How Do Plants Survive in Soilless Medium? Plants have adapted to grow in soil for millions of years. So, how do they survive in a soilless environment? Plants rely on a variety of nutrients, including nitrogen, phosphorus, and potassium, to grow and develop. These nutrients are typically found in soil, but they can also be found in a hydro

What is RNAi ? How it could help to treat cancer?

What is RNAi? Any scope of treating cancer with RNAi? In RNAi "i" stands for interference. Mitosis Meiosis cell You can think of your cells as the kitchen in a busy restaurant. Sometimes your body orders chicken. Other times, it orders steak. Your cells have to be able to crank out whatever the body needs and quickly. When an order comes in, the chef looks to the cookbook, your DNA, for the recipe. She then transcribes that message onto a piece of paper called RNA and brings it back to her countertop, the ribosome. There, she can translate the recipe into a meal, or for your cells, a protein, by following the directions that she's copied down.  But RNA does more for the cell than just act as a messenger between a cook and her cookbook. It can move in reverse and create DNA, it can direct amino acids to their targets, or it can take part in RNA interference, or RNAi. But wait! Why would RNA want to interfere with itself? Well, sometim

What are DNA Polymerases and how they works ?

  What is PCR??  Stands for "polymerase chain reaction" What are DNA Polymerases?? These are the enzymes used in the PCR.  In this article, I will cover the structure, important characteristics and the different variants of DNA polymerases. DNA polymerases are enzymes responsible for assembling nucleotides to create new DNA molecules. These DNA polymerases are indispensable to cell divisions as they duplicate the genetic information that would be passed to the next generation of daughter cells. One of the most fundamental technologies in genetic and molecular research is the Polymerase Chain Reaction also known as PCR. PCR utilizes the ability of DNA polymerase to replicate DNA strands by amplifying a large amount of DNA from a small amount of nucleicacids.  Throughout the years, scientists have utilized different variants of DNA polymerases for different applications.  All these DNA polymerases have a similar shape, in that they re

Locust plague 2020: Life history, A successful story and future food

  Life cycle of desert locust ( Schistocerca  gregaria ) Life cycle of locust has 3 main life stage - egg, nymph or hopper (5 nymphal instars) and adult. It takes about 8 weeks to  complete the life cycle.  Desert locust ( Schistocerca  gregaria) However, the duration of locust life  cycle is variable and depends on the various climatic conditions and type of species of locusts as well. As African locusts can have 3 -5 generations per year. How locust is different from grasshopper? Actually, both are same. Green grasshopper is generally solitary feeder while the brown Locusts (short horned grasshopper) are both solitary and gregarious. REASON - Increase in serotonin concentration in the  grasshopper and  favourable climatic changes turn them into gregarious (feeding in group) and devastating locusts, that can damage acres of crop in just few minutes and hours. Do they harm humans? No, they don’t
