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...

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....

In eukaryotes DNA methylation plays an important role in the transcriptional regulation of genes, silencing of transposable elements and X-chromosome inactivation to name a few. DNA is methylated by DNA methyltransferases Dnmt3A and Dnmt3B and methylation is maintained when new cells are formed by Dnmt1....

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...

A genetic disorder is a relatively rare genetic problem caused by one or more defects in an individual’s DNA. The size and severity of these abnormalities can vary, ranging from a point mutation changing a single base in one gene to entire chromosomes being affected....

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...

Polymerase chain reaction or PCR is the in vitro technique for the synthesis of the DNA or we can say that it is an in vitro DNA replication procedure. This technique is generally used in case of molecular biology for the amplification of a single...

Genetic engineering, also known as genetic modification, is the direct manipulation of DNA to alter an organism’s characteristics (phenotype) in a particular way. It is a set of technologies used to change the genetic makeup of cells to produce improved or novel organisms. An organism...

“ The cell cycle is the process in which a cell goes through leading to the duplication of its DNA and division to produce two daughter cells. It follows a cyclical structure that includes interphase and mitosis. The interphase is composed of three sub sets,...

The paper I chose for this assignment was “Regulation of the Mdm2-p53 pathway by the ubiquitin E3 ligase MARCH7” (Zhao et al., 2017). I determined that I wanted to use this paper as it directly relates to the specific lecture topics we’ve gone over already....

The cell cycle is the process in which a cell goes through leading to the duplication of its DNA and division to produce two daughter cells. It is a series of events that include interphase and mitosis. The interphase is composed of three sub sets,...

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...

The experimental techniques for investigating protein-DNA interaction are classified in two forms, i.e. in vitro and in vivo. The studies of in vivo are helpful because of the preservation of the natural structure of interaction sides. However, in multi-proteins, it is hard to figure out...

Ubiquitination, a proteasomal degradation process, is based on covalent attachment of ubiquitin to a substrate lysine on a target protein, marking the protein for its degradation. This process renews intracellular proteins balancing the rate of degradation with the rate of protein synthesis, resulting in homeostasis....

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...

Isolation of DNA is a very important technique which is the foundation for many types of techniques such as the diagnosis of many genetic diseases as well as fingerprinting DNA. How much amount and purity required, the DNA type is what makes the difference for...

There is little understood about the frequency of mutations caused by plant transformation and the potential biosafety hazards they pose on crop species. Plant transformation is often used for breeding of commercial crop by inserting transgenes into plant chromosomal DNA. However, the transgene insertion is...

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...

Advances in technology have a great influence on scientific thinking about evolutionary relationships. Technology advancements allowed more updated and accurate tests to be done so difference can be distinguished between species. Fossil records, comparative anatomy and pattern of embryonic development where the main rescores used...

The significance of plant hereditary assorted variety (PGD) is presently being perceived as a particular zone since detonating populace with urbanization and diminishing cultivable terrains are the basic variables adding to sustenance instability in creating world .plant genetics researchers understood that PGD can be caught...

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...

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...

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...

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...

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...

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...

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...

My understanding of epigenetics is directly linked to my understanding of how basic genetics itself works. Cells which are popularly known as the “building blocks of life” or the “smallest unit of life” are like little workers in every human being that plays a major...

The dawn of cancer genomics has heralded an unprecedented era of precision medicine, allowing the identification of genome-wide somatic driver alterations that can be used for early cancer diagnosis, prognosis, stratification to optimum therapies and monitoring of developing resistance, as well as predicting which patients...
