Essays on Cell

Hellen Phillips article “The Cell that Makes Us Human” gives details of a new human physiology discovery, spindle cells, utilizes the absence of the said cells from lower order animals to differentiate humanity, and other higher order primates, from the rest of the animal population. The article associates the...

Meiosis and mitosis are two different types of cell division. Chromosomes from the parent cell split into two nuclei during mitosis, creating two daughter cells. Chromosomes alter during mitosis in a number of ways, including duplication, condensation, and attachment to spindle fibers found in the cytoskeleton of the cell (Nicholas...

The immune system tries to eliminate the virus particles and remove them from the body anytime the human body is exposed to viral particles. Human cells are vulnerable to viruses. The virus can easily attach itself to the accessible cells when the immune system is compromised, which frequently causes general...

DNA sequence changes can result from cell mutations passed down from a parent organism to its children. Some cell mutations can be advantageous, but the majority are damaging because they result in the cell's ability to perform a specific function being lost. Bacteria naturally experience base pair mutations at a...

The Importance of the Endocrine System The endocrine system controls the release of hormones, which are molecules that help connect and govern different body systems. As a result, it is crucial for both human and animal health.The Role of Endocrine Disrupting Substances (EDCs) Endocrine disrupting substances (EDCs) prevent steroids from performing their...

It might be claimed that enzymes are naturally occurring catalysts that speed up chemical reactions. By offering distinct binding sites for the substrates, the enzyme catalyst enhances the likelihood that reactants will come into touch with one another in the right orientation (Madden & Shafer 2002). This experiment was specifically...

Endothelial cells, which are highly specialized to enable precise regulation of chemicals entering or leaving the brain, make up the blood-brain barrier (BBB). Endothelial cell interaction with cellular and non-cellular components controls the barrier's development and maintenance (Obermeier et al., 2013). Extracellular matrix, pericytes, and astrocytes in particular offer both...

Introduction Having one extra copy of chromosome 13 in the body cells, instead of the normal two, causes Patau's syndrome, a deadly genetic condition. Trisomy 13 chromosome 13 and full trisomy 13 are other names for it. A condition known as mosaic trisomy 13 occurs when the abnormality only affects a...

The Notch Signaling Pathway The juxtacrine or contact-mediated signaling pathway between two neighboring cells is used by the Notch Signal Pathway. During the selection of cells' fates and the development of the embryo, this kind of signaling is required (Kopan 2012). The intracellular domain that controls gene expression is released by...

A fungus called Cryptococcus neoformans A fungus called Cryptococcus neoformans is present in the environment all around the planet. The organism is a spherical, encapsulated fungal cell that is not fermenting, and it appears to be distinctive in that it has a mucinous capsule. The organism can transform into yeast cells,...

Mutation is a rare occurrence. Mutagens barely affect the procedure. Finding them is a difficulty for scientists. In the isolation of mutants, there are two techniques used. The direct and indirect selections are these. Researchers put a substrate that allows mutations to grow in the direct selection. It prevents the...

B Lymphocytes B lymphocytes, often known as B cells, are a type of white blood cell (WBCs). In essence, B cells fall under the WBC subgroup of lymphocytes. B cells are essential for the adaptive immune system because they secrete antibodies, according to Murphy (2012). The author also asserts that B...
