Numerous media(singular, medium) have been developed for bacterial cultivation. Because the nutritional requirements of bacteria vary widely, there are great differences in the chemical compositions of the media used in the laboratory. This article gives the details of Bacterial growth. Nutritional Requirements The organisms require a ‘source of energy. Some depend on chemical compounds for their energy and are designated as “Chemotrophs”. Eg: Nitrosomonas Europaea, E.Coli All organisms require a ‘Source of energy’ for their metabolism. Some organisms can use reduced inorganic compounds as electron donors and are termed “Lithotrophic”. Some Bacteria […] - [What is Buffer Solution? Types and Calculations](https://golifescience.com/what-is-buffer-solution-types-and-calculations/): A buffer solution is one that resists pH change on the addition of acid or alkali. Such solutions are used in many biochemical experiments where the pH needs to be accurately controlled. Buffer solution definition: A buffer solution (more precisely, pH buffer or hydrogen ion buffer) is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. Its pH changes very little when a small amount of strong acid or base is added to it. From the Henderson-Hasselbalch equation, the pH of a buffer solution depends on two factors: one is the pKa value and the other the ratio […] - [What is Bacterial Stress Response?](https://golifescience.com/bacterial-stress-response/): Bacteria can survive under varied conditions (called Bacterial Stress Response), and to overcome adverse situations, the changes must be sensed by bacteria and mount reactions in protein activity and gene expression. The stress reaction in bacteria involves a system of components that behave against the stimulation. Compounds can respond simultaneously to many different stresses, and the variety of stress response systems in bacteria interact (cross-talk) with every other. A network of systems that are international contributes to an efficient and coordinated reaction. These systems regulate the manifestation of effectors that maintain the equilibrium of the balance under the ailments. Bacteria […] - [What are the key structures and functions of the Mitochondria?](https://golifescience.com/mitochondria/): Mitochondrial are present in all eukaryotic cells and are the major sites of aerobic respiration within cells. they were first seen as granules in muscle cells in 1850.

MiRNAs play a critical role in gene regulation and are involved in many […] - [Colligative Properties : What are the basics of Colligative Properties and its Types](https://golifescience.com/basics-of-colligative-properties/): Like pure solids, liquids, and gasses, solutions have well-defined physical properties (e.g., vapor pressure, boiling point, etc.). A change in a property of a solvent that depends on the concentration of dissolved solute(s) particles is called colligative properties. Colligative properties do not depend on the identity of either the solvent or the solute(s) particles (kind, size or charge) in the solution. Introduction of Colligative Properties Colligative properties mean Properties of solutions that depend on the number of solute particles but not on their nature. Examples of Colligative properties are: Vapour Pressure lowering of a solution Boiling Point Elevation Freezing Point […] - [Basic Elements of Immunity and Types of Immunity](https://golifescience.com/immunity-basic-elements/): The term Immunity is defined as the resistance shown by the host against the adverse effects caused by microbes and their toxic products. Invertebrates, two types of defense mechanisms work together to contact infection. Innate Immunity (or) Non-Specific resistance Acquired immunity (or) Specific resistance Innate Immunity It is a non-specific immunity. The mechanism is similar for most types of infections, hence its name. Its resistance to infection is by blocking the entry of pathogens into the body or by destroying the microbes through means other than antibodies. Thus non-specific defense mechanism provides innate immunity which operates through many factors. First-line […] - [What are the Enzymes involved in DNA Replication?](https://golifescience.com/enzymes-involved-in-dna-replication/): A fundamental property of living organisms is their ability to reproduce. Bacteria and fungi can divide to produce daughter cells that are identical to the parental cells. Sexually reproducing organisms produce offspring that are similar to themselves. This article covers the Enzymes Involved in DNA Replication.  On a cellular level, this reproduction occurs by mitosis, the process by which a single parental cell divides to produce two identical daughter cells. In the germline of sexually reproducing organisms, a parental cell with a diploid genome produces four germ cells with a haploid genome via a specialized process called “Meiosis“. In both of […] - [Theories of Organic Evolution Explain the Origin of Life (Complete Notes)](https://golifescience.com/theories-of-organic-evolution/): The Theories of Organic Evolution explain the convincing origin of life. It also explains how the wide variety of plants and animals came into existence in the world. According to this theory, the world has evolved and not been created. Life originated spontaneously in the remote past from non-living inorganic substances. These substances reacted to organic compounds. The organic compounds developed into colloidal systems capable of stepwise improvements in order to give rise to a simple life. Basic Theories of Organic Evolution In organic evolution, there are different theories of evolution. But five theories are accepted universally. They are 1.

The primary functions of chromatin are: to package DNA into a smaller volume to fit in the cell, to strengthen the DNA to allow mitosis and meiosis and prevent DNA damage, and to control gene expression and DNA replication. The primary protein components of chromatin are histones that compact the DNA. Chromatin is only found in eukaryotic cells. Prokaryotic cells have a very different organization of their DNA which is referred to as a genophore (a chromosome without chromatin). The structure […] - [What are Buffers and What is the Importance in Biological system?](https://golifescience.com/buffers-importance/): Buffers are the mixture of weak acids and their salts of strong bases (or) the mixture of weak bases and their salts of strong acids. Buffers help to maintain a normal pH of the biological systems. When an acid (or) alkali has added the pH of the solution changes in the absence of buffers. What is Buffer in Biology? An acid-base balancing or control reaction by which the pH of a solution is protected from major change when acid or base is added to it. The same effect can be obtained by the use of a blend of two acid […] - [What is DNA Polymerase and its function in DNA Replication](https://golifescience.com/dna-polymerase/): The first postulate the central dogma, experimentally proved and is that the DNA is capable of self-replication. This was immediately deduced by Watson and Crick that each DNA strand uniquely specifies its complement, but it took longer for the details of the mechanism are elucidated. The first question was that of the conservation of the replication mechanism.  The now-classic experiments of Meselson and Stahl proved that DNA replication is semi-conservative, in that each of the sister molecules inherits one strand of the parental DNA.  It would have been perfectly possible to imagine a conservative mechanism, where the two strands of the […] - [What is Fidelity of DNA Replication in Normal?](https://golifescience.com/fidelity-of-dna-replication/): DNA replication is, by far, the most accurate of known enzyme-catalyzed processes. The error rate per base pair per round of replication is about 10-9 to 10-10. The accuracy cannot be explained, however, by the different binding energies between correct and incorrect base pairs (this amounts to only a 100 to 1000 fold difference between correct and incorrect pairing). This article explains the fidelity of DNA replication. Enzymes involved in DNA Replication What is the Fidelity of DNA Replication in Normal? Two cellular systems aid the fidelity of DNA replication. These include the following: The 3′->5′ exonuclease activity of DNA […] - [What are the importance of Coupling Reactions in Biological Systems?](https://golifescience.com/coupling-reactions/): What is a coupling reaction? Before going to discuss this, we need to know about Energy. Energy is the capacity to do work and appears in many different inter-convertible forms: light, heat, electrical, mechanical, and so on. Energy can be kinetic (‘active’) or potential (‘stored’). The water behind a dam represents a store of potential energy that could be released to give the kinetic energy of motion. Everyday experience tells us that all processes may be dividing into two categories those that tend to go by themselves which may be thought of as energy-releasing and those that do not unless […] - [Bioenergetics: Study of Free Energy Transformation and its changes](https://golifescience.com/bioenergetics-energy-transformation/): Thermodynamics is the branch of physical chemistry that deals with energy changes and Biochemical thermodynamics (or biochemical energetics of bioenergetics as it is also called) is the field of biochemistry concerned with the energy transformation and use of energy by living cells (Energy transformation).
