Essays on DNA

It is joining together of DNA molecules from two different species that are inserted into a host organism to produce new genetic combinations that are of value to science, medicine, agriculture, and industry. Since the focus of all genetics is the gene, the fundamental goal...

DNA replication is a multi-step process that is essential to cell division. If DNA is replicated incompletely or incorrectly, then dysfunctional proteins will be produced. Proteins that are dysfunctional or incomplete are undeniable symptoms of DNA mutations and causes of diseases and terminal cancers. As...

Human genome contains all the information necessary to maintain and continue the life, and two basic processes are most important for that. One is a transcription of genetic information which leads to synthesis of proteins and another one is a replication and maintenance of the...

The Human Immunodeficiency Virus (HIV) has affected millions of people worldwide, more especially in sub-Saharan Africa. The number of infections that occurred in infants in 2014 was estimated at 220, 000. Out of this, approximately ninety mine percent of the infections in infants are acquired...

Abstract DNA can be transferred by touch. This touch DNA is used to gain information to help with criminal investigations, disaster victim identification or eve missing persons (Sankhla and Kumar, 2017). The significance value of DNA profiling had increased in forensic investigations over time and...

Rosalind Franklin was born in a wealthy Jewish family in London, England. Franklin’sfather, Ellis Franklin, was a professor of electromagnetics and World War I history at Working Men’s College and later became a president of the school. Her Father’s first name is also hermiddle name....

Many chemical agents have a property of causing damage to the DNA which may lead to cancer are called as genotoxins and this property of such chemical agents is called as genotoxicity. Genotoxicity is generally confused with mutagenicity but they show a few differences in...

Alternations of chromosome number or structural changes of chromosomes appear quite often in hybrids. Those changes can result in genetic diversity or can even drive to new species formation. Chromosome aberrations can be triggered as a result of physical factors (such as: radiation, temperature), chemical...

DNA are molecules in the chromosomes that contain your genetic information. Every human has a different set of DNA. The first person to study DNA was the Swiss chemist, Johann Friedrich Miescher, in the 1860s. Some of the famous pioneers who contributed to the study...

Brief Introduction In modern society, when people are enjoying the convenience brought by powerful technology and science, they also hope to keep this status forever. This, without doubt, leads us to the word: immortality. In order to learn this term, it is easy to start...

With each passing minute, the world population increases by hundreds, and to support the ever-increasing population, food is required. To cope up with this food demand, various methods are being devised since decades. A recent one under discussion is ‘Gene Editing’. This method, unlike any...

The cancer stem cell (CSC) hypothesis is regarded as a reasonable explanation for the rapid multiplication of cells in the disease. They are self-sufficient cells which seem to have increase tumorigenicity and self-renewal, which allow them to expand more rapidly than normal cells. While the...

Future of chronological age estimation in Forensics*Anjali Abstract DNA methylation is an epigenetic mechanism which plays a vital role in the control and regulation of gene expression. In the past few years DNA Methylation was widely investigated in Medical field to understand complex diseases, but...

Kibera is the largest informal settlement in Nairobi, Kenya and one of the largest in Africa and the world. It is is located 7km southwest of Nairobi and houses approximately one million people and several animal species. Conditions in Kibera are extremely poor and heavily...

Introduction For the past two decades, personal technology has made incredible advancement, bringing us into a fast paced, digital world that we live in today. In the 1980s we had supercomputers that took up the space of a whole room and today we all have...

The case investigation of the remains of a burned body began when a janitor noticed the remains at the bottom of a dumpster while going to throw out the trash in Vancouver, British Columbia. There were many problems encountered in this case investigation. Firstly, it...

Electrochemical Detection Most of The tumors have markers in blood and serum which can be monitored [65,66]. An electrochemical immunosensor is special device applied for tracking of some diseases, in which a sandwich immunoreaction is commonly applied on an electrode surface (see Figure 6), such...

Introduction Man by nature is a fighting animal, hence to think of a crimeless society is a myth. Truly speaking, there is no society without the problem of crime and criminals. The existence of crime is established from the time of Adam. The Bible and...

Abstract Poaching of wildlife for local consumption and commercial purposes is a major threat to the loss of world’s biodiversity which has even resulted to the extirpation of the numerous species at local or regional scale. Law enforcement agencies have been working in the implementation...
