1 Introduction 1.1 Motivation The gene is the basic unit in deoxyribonucleic acid (DNA) which contains the required information to carry heredity. The expression of genes is a process in which a functional gene product is synthesized from DNA using gene information. In gene expression, transcription factors play a very important role. Transcription factors are […]
INTRODUCTION Cancer is a complex lethal disease that is only now being understood on the molecular level. Primarily due to the variety and complexity of tumors, cancer treatment has previously been approached only through direct therapies aimed at blocking proliferation or inducing apoptosis of any rapidly dividing cell population. However, rapid advances in cancer research […]

Get startedHistoria da minha vida Pelo dia 31 de Maio de 1983, após 9 meses na barriga da minha mãe já todos me esperavam, principalmente meus pais Luísa da Silva Alves e José Luís Ribeiro da Costa e também minha irmã Liliana Sofia da Silva Ribeiro, mais velha que eu 6 anos. Então lá nasci eu […]
Human Genome Project: Legal, Ethical and Social Implications In this dissertation we consider the human genome project in its wider context. We take a brief overview of the aims, the working and the sequencing techniques used together with the timeline achieved. The ability to sequence genes has given a greater understanding of the human genome. […]
Abstract Recent advances in DNA sequencing technologies have led to efficient methods for determining the sequence of DNA. DNA sequencing was born in 1977 when Sanger et al proposed the chain termination method and Maxam and Gilbert proposed their own method in the same year. Sanger’s method was proven to be the most favourable out […]
Last time this market had a major wave of innovation was over a decade ago which started with big technological advances due to new funding for new ventures, but resulted in the rise of a sole technologies provider who dominated the market and stunted technological advancement. Now, the emergence of a new wave, the Next […]
Whilst prokaryotes do not have a structured nucleus and other composite cell organelles found in eukaryotic cells, prokaryotic beings allocate the some general features with eukaryotes with the knowledge of cell division is, For instance, they both reproduce DNA in a semi traditional manner, and the separation of the lately formed DNA molecules can transpire […]
1. Introduction 1.1 DNA Structure DNA is a polymer made of subunits called as nucleotides. Each nucleotide consists of a deoxiribose sugar, a phosphste, and a nitrogenous base (Genetics from Genes to Genomes). Watson and Crick proposed the structure for DNA (shown schematically in Figure 1 a). This is the presence of two polynucleotide strands […]
Preliminary Thesis: –>“Genetic engineering should not be controlled by the law, because the people controlling the law are not credited on knowing about what it is they are controlling. ” 1st Revised Thesis: –>“The government shouldn’t have the power to control Genetic Engineering; because Government Legislators do not possess the adequate degree, and/or satisfactory knowledge […]
Because all DNA polymerases synthesize DNA in the 5-to-3 direction, and the parental strands are antiparallel, DNA replication is accomplished with the use of two mechanisms: continuous and discontinuous replication. Indicate whether the following items relate to (1) continuous replication, (2) discontinuous replication, or (3) both modes of replication. Indicate whether the following statements are […]
Neuroscientist Kevin Pelphrey has decided to study autism and it’s origins at the University of Virginia in Charlottesville. As of now, there is no well developed idea on why exactly certain people are on this spectrum. Scientists have decided there is no single reason that could be an outright cause or trigger of autism, rather […]
ABSTRACT: In this experiment, deoxyribonucleic acid (DNA) was extracted from Micrococcus lysodeikticus, a bacteria with a high guanine and cytosine content. The standard method of chloroform-isoamyl alcohol extraction was used, and the DNA was solubilized in Tris buffer. The DNA was then quantified and qualified using UV spectrophotometry. The DNA was determined to have been […]
Have you ever wondered if it is possible to cure cancer, have genetically related babies from same-sex parents, completely eradicate mosquitoes, resurrect an extinct species, or even insert a GIF into bacteria and have the bacteria replicate the GIF? With technology becoming more advanced by the hour, increasing possibilities are arising. In 1993, certain segments […]
Despite efforts to maintain wildlife conservation as well as biodiversity, many endangered animals are coming closer to the brink of extinction. The current method of preserving genetic diversity in endangered species is to keep them in containments such as zoos. Unfortunately this leads to animals being kept out of their natural habitats, in limited spaces, […]
Having an abnormal number of chromosomes is known as aneuploidy. Aneuploidy opens the window for many possible diseases, and among these are down syndrome, acute lymphocytic leukemia, and acute myeloid leukemia. Normally, baby fetuses have 46 chromosomes; 23 from the sperm cell and 23 from the ovum. However, if there is an abnormal number of […]
Thesis: There are multiple points to support that the practice of genetic engineering helps us as a society, but there are other sides arguing that the genetic modification of humans and animals is unjust. They also say that genetically modifying foods serves no purpose for health. This practice has upsides and downsides, this causes controversy […]
HISTORY OF GENETIC ENGINEERING Curiosity is one of the natures of mankind, it is to surprise that we ventured down the road of genetic engineering to find ways to make living easier for us. Genetic engineering has been occurring even far back to the Bible days without knowledge of it. Most people that are […]
With an increased awareness of the human footprint being left on Earth, there has been a shift in many science fields to find ways to improve sustainability. Following the 1987 Brundtland Report, sustainability was defined and categorized into three parts. According to this report, sustainability is the development of services and methods to meet the […]
Disease, drought, malnutrition, pests, malfunctioning genes are all factors are all problems that society faces. Only until recently a new method of solving these problems was discovered, genetic engineering. Genetic engineering refers to the process of manipulating an organism’s DNA to change its traits. This practice can be applied to plants, animals, and humans. It […]
DNA (deoxyribonucleic acid) has significantly impacted the scientific world since it was fully decoded by the Human Genome Project in 2003. The Human Genome Project was a 13 year project to fully sequence the human genome, and find the similarities and differences throughout the human race. The value of the project [ ] appears beyond […]
Introduction DNA evidence is the use of body products like saliva, blood, skin cells, semen, and any biological material to develop investigative leads. Forensic DNA analysis is accurate and reliable, and as a result, its evidence is essential in exonerating people who are convicted wrongly. The popularity of DNA evidence has captured the headlines as […]
