Essays on DNA

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…

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…

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…

Types of Cell Reproduction There are two ways for cells to reproduce: asexual and sexual reproduction. Asexual reproduction of cells is the reproduction of all cells in the body(ie: stomach and skin cells) excluding the gametes which are the sperm and egg cells. The reproduction…

In vitro fertilization laboratory is to get the best ratios between the number of oocytes retrieved and the ratio of embryo production which are highly viable. First step is obtaining the oocyte and spermcells from the patients. Then to improve the success rates we use…

For example, if the adult participant’s mother and both sisters have diabetes, hypertension, or cancer, what might that mean for the adult participant’s future health? An adult participant’s health could be highly affected by the family’s genetic history. As per the information collected about the…

The macrophages mount an effective host defense by recognizing, engulfing and killing M. tuberculosis. The recruitment of macrophages is through Toll-like receptor (TLR) mediated signaling that is triggered by pathogen activated molecular patterns (PAMPs) present on bacterial surface. The infected macrophages transport the bacteria across…
