Plant DNA C Values
Introduction Regardless of the species' level of ploidy, the C-value refers to the quantity of nuclear DNA in the unreplicated gametic nucleus. A carnivorous herb called Genlisea margaretae has a genome size of 0.129 pg (63 Mbp), whereas the monocot Trillium hagae has a genome size of 264.9 pg (for reference, Arabidopsis thaliana has a genome size of 0.321 pg; Bennett and Leitch, 2005; Zonneveld et al., 2005; Greilhuber et al., 2006. The plant C-value database contains C-value information for more than 5000 plant species. Genome Size The total amount of DNA in the unreplicated haploid nucleus, or ...
Read MoreMolecular Genetics and Biotechnology
Introduction Basic molecular genetics research has created brand-new possibilities for illness diagnosis. The potential to translate research results into practical applications in industry is enormous. A branch of biology that studies how variety in animals arises from variations in the structures or expression of DNA molecules is called Molecular Genetics. Genetic screens are frequently used in molecular genetics to "investigate" the structure and/or function of the genes in an organism's genome. Cellular biology, molecular biology, biochemistry, and biotechnology, as well as traditional Mendelian inheritance, provide the foundation of the field of study. To connect a gene sequence to a ...
Read MoreHistory of Plant Cell and Tissue Culture
Tissue Culture Tissue fragments from animals or plants are transplanted to an artificial environment where they can continue to thrive and function as part of the biological research technique known as tissue culture. One cell, a group of cells, an entire organ, or a portion of an organ may make up the cultured tissue. In culture, cells can divide, alter their shape, size, or function, engage in specialised activity or collaborate with other cells. Introduction to Culture Media Biological culture media, such as blood serum or tissue extract, chemically defined synthetic media, or a combination of the two may ...
Read MoreEnvironmental Biotechnology: An Overview
Introduction Environmental biotechnology is biotechnology that is used to understand the environment and is applied to it. Environmental biotechnology may also suggest that one tries to control biological processes for profit. Environmental biotechnology is described as "the development, use, and regulation of biological systems for remediation of contaminated environments (land, air, and water), and for environment-friendly processes (green manufacturing technologies and sustainable development)" by the International Society for Environmental Biotechnology. Definition The simplest definition of environmental biotechnology is "the best use of nature, in the form of plants, animals, bacteria, fungi, and algae, to produce renewable energy, food, and nutrients ...
Read MoreCulture Media: Types and Uses
Introduction A growth medium, commonly known as a culture medium, is a solid, liquid, or semi-solid that is intended to foster the growth of a population of microorganisms, cells, or miniature plants, such as the moss Physcomitrella patens, through the process of cell proliferation. Various cell types are grown in various types of medium. Growth Media The two primary categories of growth media are those used in cell culture, which employ certain cell types obtained from plants or animals, and those used in microbiological culture, which are used to grow microorganisms like bacteria or fungi. Nutrient broths and ...
Read MoreCellular Biotechnology: An Over View
Introduction Only with development of the compound microscope during 17th-century in Europe, cells were first observed. After gazing at a piece of cork and noticing a cell-like structure, Robert Hooke coined the term "cells" (published in Micrographia) in 1665. Nevertheless, the cells were dead and gave no hint to the true overall components of a cell. Just few years later, in 1674, during his investigation of algae, Anton Van Leeuwenhoek became the first to examine live cells. All of this came before the cell theory, which argues that cells are the basic building blocks of life and that they make ...
Read MoreDifferences between Magnitude and Intensity
When we talk about physical quantities, it is essential to understand the difference between magnitude and intensity. In simple terms, magnitude refers to the size or quantity of something, whereas intensity is a measure of how strong or powerful it is. In this essay, we will explore the key differences between magnitude and intensity and their applications in different fields of science and engineering. What is Magnitude? Magnitude refers to the size or quantity of something. It is a scalar quantity that can be measured or expressed in terms of a numerical value. For example, the magnitude of a vector ...
Read MoreDifference Between Collagen and Biotin
Collagen and biotin are two essential substances for maintaining a healthy body. Both collagen and biotin play a vital role in maintaining healthy skin, hair, nails, and joints. However, there are many differences between the two substances, including their functions, sources, and benefits. What is Collagen? Collagen is a type of protein that makes up about one-third of the total protein in the human body. It is the primary component of connective tissues such as skin, tendons, cartilage, and bones. Collagen is responsible for giving skin its elasticity and strength and for maintaining the structure of bones and joints. As ...
Read MoreSimilarities and Differences between Memory T Cells and Memory B Cells
Introduction Memory cells are long-lived immune cells capable of recognizing foreign particles that they had encountered previously. Memory cells capture the antigen or components of foreign antigen that invades our body and provides protection against them very fast when compared to the initial attack. Antigen exposure and its immune response usually 2 types Initial Exposure – Primary immune response, here the memory does not take part in providing an immune response. Secondary Exposure (when a similar kind or same antigen attacks the immune system) – Here memory cells start initiating the secondary immune response Here the time ...
Read MorePlasma - Amber-Colored Liquid Component of Blood
Introduction Blood plasma is the fluid portion of the blood which is usually transparent and straw-colored. The importance of blood is mainly due to the plasma as it is the one which carries a lot of important material and transports it throughout the body. Plasma is usually isolated as a clear fluid along with the RBC, WBC, and platelets when we centrifuge the blood. RBCs are the heaviest and usually settle down at the bottom of the centrifuge tube, white viscous coat found in the middle contains WBCs and platelets and the upper layer of the tube contains plasma. ...
