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…
Introduction As we rapidly progress through the new millennium genetics comes down from pages of since-fiction novels into our lives. What we thought was not possible only 30 years ago now can be done in a matter of days. I am obviously talking about genome…
Since the structure of DNA was determined in the 1950s, scientists have continued to make great advancements in establishing how the “building blocks of life” are intertwined. In 2003, the Human Genome Project was completed. At the time, the cost for the first individual to…
Introduction DNA is the key to understanding all life forms. Many techniques have been discovered throughout the years in the race to be the first research team to code the human genome. The human genome project (HGP) began in 1990. It was an international project…
Introduction Twins leave many people pondering a variety of questions. The two different types of twins have various similarities and differences. Identical twins’ similarities are be caused by a combination of genes and the environment. Researchers have been trying to distinguish the difference between the…
Abstract Wilson Diseases is a genetic disease prevents the body from removing extra copper. It is an autosomal recessive disease. Wilson Diseases is a rare autosomal recessive inherited disorder. The objective of this research is to predict or detect/find Wilson syndrome genetic disease from the…
