Essays on Genetics

Down syndrome is a genetic disorder that causes intellectual disability and other physical and learning challenges. It’s also called “trisomy 21” as it caused by the existence of an extra copy of chromosome 21 (Pregnancybirthbaby.org.au, 2019). The person who was pictured with down syndrome was…

Meiosis in angiosperms (flowering plants) occurs within the floral organs of the plant and is defined by two major features: recombination of the pre-meiotic chromosomes and the reduction of ploidy in half. The ploidy is reduced in half because a single round of DNA replication…

Erythrosine (disodium salt of tetra iodofluorescein) an artificial red dye (cherry-pink) vastly used in food, pharmaceutical and cosmetic colouring made from coal tar (Combes and Haveland-Smith, 1982). According to the World Health Organization iodine may be affect thyroid which leads to thyroid tumors. Erythrosine gives…

Defective disjunction of sister chromatids can arise due to aberrant DNA structures that are mainly detected during anaphase and are known as ultrafine anaphase bridges. These bridges have to be repaired otherwise the bridge persists into cytokinesis and could give rise to chromosomal instability. Ongoing…

Until this day down syndrome is still one of the most common disorders. Centers for Diseases Control and Prevention (CDC) states, that “Each year, about 6,000 babies are born with Down syndrome, which is about 1 in every 700 babies born.” There are three types…

The number of people affected by cardiac problems every year is rising globally and one of the many actions taken to address this broad concern is employing tissue engineering techniques for cardiac tissue repair and regeneration. Although, there are limitations in the ability of human…

The mammalian heart has been considered for long time as a terminally differentiated organ incapable of regenerating after injury. In recent years, many evidences demonstrated that cardiomyocytes, during aging and after injury, are able to reentry in the cell cycle and promote cells renewal [Ahuja,…

Genetically modified organisms (GMO) are everywhere in this day in age, which is causing a lot of controversy. Some saying there are potential risk and others saying it’s a great way to protect and increase yields which cut cost. Commercial sale of genetically modified (GM)…

Everything is evolving. Not just humans and animals, but our food too. Some say it started way before humans even knew about genetics and how to alter genes. Decades before organisms began to be genetically modified, animals were indirectly modified through selective breeding. But now…

Did you know that most of the time you are consuming GMOs? In recent years, geneticists in order to make profit have replaced our diet with genetically altered foods, which have adversely affected human health and local communities. Being resistant to pesticides, GMOs are created…
