Essays on DNA

In the 1980’s, DNA analysis were found and had became a great advance crime-solving tool for investigators. DNA analysis were created to be used in crime cases and it can help clear suspects and identify criminals. Also, television shows like “CSI” had helped increase 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...

Introduction 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...

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...

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....

What is PCR? 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...

Beyond The Central Dogma Genetic Science Learning Center The principal dogma of molecular biology explains that DNA codes for RNA, which codes for proteins. Within the crucial Dogma, you can find out about the vital roles of messenger RNA, switch RNA and ribosomal RNA within...

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...

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...

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...

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 as a...

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...

One of the greatest scientific adventures ever and at the heart of it is a small very powerful molecule DNA known as “The Secret of Life.” The human genome project showed that the majority of the 3 billion base pairs which is 99% are stuff...

The well-defined group is L. acidophilus dividing in Lactobacillus phylogenetic subgroups. Its meaning although is moderately built by DNA-DNA homology, 32% to 50% constituent content existing in genomic (GC) species (Felis & Dellaglio., 2007). In between ephemeral and permanent resident of normal gut flora Lactobacillus...

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 Heredity is the transmission of genetic characteristics from ancestor to descendant through the genes. As a subject, it is tied closely to genetics, the area of biological study concerned with hereditary traits. The study of heritable traits helps scientists discern which are dominant and...

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...

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...

Studies in E. coli primarily led to the discovery of the detailed mechanism of prokaryotic transcription. Overall, it appears that prokaryotic transcription requires the DNA double helix to partially unwind in the region where mRNA synthesis takes place. This region of unwinding is known as...

Matthew Meselson and Franklin Stahl are famous for their DNA replication experiment. Meselson and Stahl conducted the experiment which supported the hypothesis made by Watson and Crick that DNA replicates. The purpose of the experiment was to provide an explanation for James Watson and Francis...

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...

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....

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...

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...

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...

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...

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...

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...

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...
