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...

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...

Gene therapy was first discovered in the mid 1970’s where researchers were able to isolate certain type of genes from DNA. The term gene therapy came about in the 1980’s and pushed research further. When we’re born each individual are born with a set of...

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....

QUANTITATIVE TRAIT LOCI Most biological traits have a multi factorial (or complex) inheritance, which indicates that they are influenced by numerous genes and environmental factors. A chromosomal region that contains one or more genes that influence a multi-factorial trait is known as a QTL. The...

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...

Inside a tumor, cells are constantly growing, multiplying and dying. When cancer cells die, they leave behind clues that are transforming scientists understanding of the disease. Dying cancer cells breakup into microscopic bubbles which can contain all sorts of molecules including chunks of the cells’...

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...

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...

DNA methylation DNA methylation is a mechanism that causes a methyl group to bind to the DNA thus modifying the groove that RNA polymerase binds to therefore inhibiting transcription. The methylation occurs on “CpG sites” which are sites of C and G bases occurring consecutively,...

Understanding the structure of the human genome allowed scientists to study the actual function of specific genes, which is very important in understanding health and disease. DNA microarray is one technique that enhances the understanding of the genome from structure to function. A microarray is...

Solving crime in the present has been made easier with the introduction of a DNA database in the UK. The database consists of millions of peoples DNA which greatly assists in future crimes and investigations as if DNA is present at a crime scene the...

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...

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...

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...

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...
