Apurinic and apyrimidind (abasic or AP) sites are the most common DNA lesions that have the ability to block replicative polymerases. Stem cell-specific 5-hydroxymethylcytosine-binding protein (HMCES) covalently crosslinks to the AP site and prevents genome instability. An HMCES DNA-protein crosslink (DPC) with an AP site within a 3Ⲡoverhang DNA is able to shield the Ap site from endonucleases and...

INTRODUCTION METAVERSE Dual-Chain is a block-chain system that satisfactorily implements the Dual-Chain Network Setup or Architecture (DNA) in providing optimum and satisfaction-level scalability, security, inter-operabililty and de-centralization. Metaverse, is not just different from other chains, but comparatively more beneficial and it offers optimized features. Unlike in other chains where one functionality or feature's quality is compromised for the other, Metaverse,...

Deoxyribonucleic acid (DNA), a self-replicating material which is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information. DNA was discovered in 1860. The molecule now known as DNA was first identified in the 1860s by a Swiss chemist named Johann Friedrich Miescher. Johann set out to research the key components...

Introduction The advent of genetic engineering has ushered in an era of unprecedented scientific possibilities, sparking significant debate over its ethical implications. Genetic engineering involves the direct manipulation of an organism's DNA to alter hereditary traits, a capability that holds potential for revolutionary advancements in medicine, agriculture, and environmental conservation. However, alongside these promising prospects, the ethical concerns surrounding genetic...

A eukaryotic cell is a cell that incorporates DNA which is surrounded by a nucleus. Prokaryotic cells and eukaryotic cells have a few things in common that cells have. The endosymbiotic idea clarifies how eukaryotic cells have evolved from prokaryotic cells that lived collectively. Prokaryotic cells do not have any nucleus and are not membrane bound organelles in which as...

Viruses have continuously challenged our perception of what âlivingâ means. The scientific community have constantly debated whether viruses are classified as living or non-living organisms. Viruses are very important complexes of biochemical that influence all types of living organisms including bacteria, yeast, plants and animal cells. Viruses are blobs of RNA or DNA surrounded by a coat of protein. They...

Introduction Fetal growth restriction (FGR) is one of the major obstetric complications that has been associated with term consequences as poor postnatal outcomes, perinatal morbidity, and mortality. (1). Nowadays, early prediction of FGR is the primary goal in maternal-fetal medicine, followed by prevention strategies in the antenatal period. Many thriving screening models like combining biochemical markers with Doppler were studied,...

In this class I have really enjoyed learning about the issues in Biology. In rating the issues we have discussed in class from most important to least important I would list pandemics and genetics/cancer as my top two choices, followed by natural selection/evolution, sustainability, human population, biotechnology/GMOâs and, lastly, climate change. I chose to put pandemics at the top of...

Introduction Behavioural genetics can be defined as the study of genetics that is used to investigate the difference in nature and behaviour in livestock. It focuses on the influences of genetics mainly the genetics and the environment influences. The concept was discovered by Francis Galton in the 19th century. However, the survey of the literature on genetics was discovered recently...

INTRODUCTION The study and research of biomedical science involves uncovering the secrets of the human body whilst developing an understanding of disease, diagnosis, and treatment (Heitman, E. 2000). This means biomedical scientists must not only understand how to treat a disease, but must understand what caused that disease, how that disease can be identified and differentiated from other diseases, how...

INTRODUCTION Everyone wishes to attain and maintain healthy body weight. However, the weight that one gains is influenced by three main factors which are: genetics, diet, and aerobic physical exercises (Singh, Kumar, & Mahalingam, 2017). A healthy weight is defined as body weight that doesn't increase one's probability of developing comorbid weight-related problems such as type II diabetes mellitus, hypertension,...

âThe Social Life of DNAâ by Alondra Nelson goes in depth explaining how genetic testing can be the key to discovering our roots. Nelson highlights the concept that people, specifically African Americans, should rediscover their roots to find out who they are and where they came from. Through DNA testing, such as 23andMe and AncestryDNA, people were able to gain...
