    Cells are the essential component of life, comprised of billions of molecules. Molecules such as DNA, lipids, proteins, RNA, glycans, and small molecules that have defined molecular properties and biological activities. Every cell has the ability to respond to its environment and to communicate with other cells to create organs, tissues, and whole organisms. Cell and Molecular Biology is a field that bridges the fields of chemistry, structure and biology as it pursues to comprehend life and cellular

    A cell is the smallest structural and functional unit of an organism. A cell is typically microscopic and consists of cytoplasm, a nucleus and enclosed in a membrane. For the information, a cell also has reproduction same like human, animal and plant. Due to Rudolf Virchow (1855), a German physician said that “Where a cell exists, there must have been a pre-existing cell, just as the animal arises only from an animal and the plant only from a plant”. He can be concluded that this concept with the

    of the cell. The Nucleus, a membrane-bound structure of a cell, plays two crucial roles in controlling the cell. The nucleus carries the cell's genetic information that determines if the organism will develop, for instance, into a tree or a human; and it directs most cell activities including growth, metabolism, and reproduction by controlling protein synthesis. The presence of a nucleus distinguishes the more complex eukaryotic cells of plants and animals from the simpler prokaryotic cells of bacteria

    Because cells are the ‘basic unit of life’, the study of cells, cytology, can be considered one of the most important areas of biological research. Almost every day on the evening news, we are told about new discoveries in cell biology, such as cancer research, cloning, and embryology. (https://highered.mheducation.com/sites/0073031216/student_view0/exercise3/the_importance_of_cell_biology.html)  This report provides an insight into the differences in the structure of cells and the way that they

    Cell Biology Cells are the basic structural and functional unit for all living organisms. They vary in size but are compartments that hold all of the biological components that are required to keep an organism alive and functioning correctly. Some organisms are singled cells such as bacteria, more complex forms like the human body are multi cellular. Cells are the smallest unit of life that can replicate independently. Levels of Organization Everything in the world (all matter) starts as an atom;

    comes to biology and in particular cell-division cycle. All organisms are constantly dividing and growing throughout their life time. The cell-division cycle in eukaryotes is a complex process that involves cyclins, cdks and multiple checkpoints that eventually lead to cell division. There are two different types of cell division which are Meiosis and Mitosis. Meiosis is the type of cell division which involves gametes or sex cells that are involved in sexual reproduction. This type cell division

    and sulfur. Carbon atoms can also bond to other carbons, forming the carbon skeletons of organic compounds. 3. Most macromolecules are polymers. Carbohydrates, lipids proteins, and nucleic acids are the four major classes of organic compounds in cells. Some of these compounds are very large and are called macromolecules. Most macromolecules are polymers, chains of identical or similar building blocks called monomers. Monomers form larger molecules by condensation reactions in which water molecules

    Arabidopsis Culture Cell and Transformation Arabidopsis thaliana (L.) Columbia ecotype suspension- cultured T87 cells were maintained at 22°C in JPL3 medium with continuous illumination and shaking at 100g. Two-week-old cells were sieved through 500 μm stainless mesh and the remaining filtrate was transferred to a flask containing 20 ml of fresh JPL3 medium for subculture. Transformation of T87 cells was done by culturing the cells in B5 medium supplemented with 1 μM 1-naphthaleneacetic acid (NAA)

    influx of Na+ ions (Patrick & Stallcup 1977). Thus, depolarization at muscle cell membrane and the neuromuscular transmission are blocked. When the neuron is stimulated, the contraction of the respiratory muscle will not be able to occur as the signals cannot be transmitted to the muscle (Young et al., 2003). This results in muscular relaxation and paralysis of the respiratory muscles which could also lead to death. The mast cell degranulating peptide (MCDP) has both inflammatory and anti-inflammatory
