DNA: what is yours Worth?

Words: 2389 Pages: 8 3943

Introduction The HeLa cell was discovered in 1951 from a cervical tumor taken from a cancer patient named Henrietta Lacks. These cells were important because they did not die after a few days like previous ones did because they were able to create a cell line. If one cell died, scientists used another one from the same sample. (1) These cells have led to scientific breakthroughs and new treatments and information surrounding the human body. The primary ethical question in […]

Mitosis and DNA Molecule

Words: 566 Pages: 2 4232

Replication is the copying of the genetic information from one DNA molecule into another DNA molecule. Mitosis and meiosis are similar in the fact that they make new cells. Mitosis replaces and repairs body cells, while meiosis makes gametes like eggs and sperm. Mitosis has an asexual reproduction, while meiosis has a sexual reproduction. These two reproductions have differences in its number of divisions, phases, chromosome numbers, etc. One difference between mitosis and meiosis would be their production of daughter […]

HeLa the Immortal Cell

Words: 1699 Pages: 6 5412

Cells are the basic building blocks of life and make up all living organisms. There are two classifications of cells in every organism called prokaryotes and eukaryotes. A prokaryotic cell composes of single cell organisms like bacteria for example. While, a eukaryotic cell consists of multicellular organisms, the example for that is humans. The human body contains 75 trillion cells and each has its specific purpose and functions that they carry out throughout the human body. The human body is […]

Role of P53 Protein in DNA Repair Mechanism

Words: 680 Pages: 2 4387

One of the most known tumor suppressors is p53 which has very low concentration because of short half-life time. Reason for this short half-life is E3 ubiquitin ligase MDM2. MDM2 is one of the genes regulated by transcription which p53 regulates. Increased p53 levels result also increased of MDM2 transcription rate, followed by this, it results the degradation of the p53 protein, forming an autoregulatory circuit in cells. There are various stress situations that can cause this such as telomere […]

Innate Immune Recognition of DNA

Words: 598 Pages: 2 4119

The cGAS is an innate immune sensor that detects double-stranded DNA. Detection of foreign DNA is an evolutionarily conserved mechanism that alerts the host immune system to mount a defense response to pathogen infections. But, there is also a challenging side for the host that how they distinguish the foreign DNA with the much abundant self genome. The presence of self or foreign DNA in the cytoplasm is sensed by eukaryotic cells as a danger signal or a sign of […]

The History and Applications of Forensic Science

Words: 1455 Pages: 5 1714

Forensic science is the application of science to law. It entails the use of these scientific processes and methods in combating crimes. There are several branches of forensic science, such as: entomology, pathology, odontology, criminalistics, psychology, geology, computing, anthropology and chemistry (Dominick et al 2009). Forensic science comes in handy during investigation of fires, trace evidence, toxicology and forensic biology among others. The society has become more reliant on the laws governing the activities of its members. It applies to […]

DNA and Mutations

Words: 277 Pages: 1 5345

Occurrence of mutation. Mutation is the process that produces a gene or a chromosome set different from the wild type. For instance this allows us to measure the frequency of mutation occurance.a cell caring mutation can be used as probes to disassemble the constituent parts of a biological function and to examine their workings and interrelations.For a recessive mutation to give rise to a mutant phenotype in a diploid organism both alleles must carry the mutation but one copy of […]

The Role of Forensic Science in the Criminal Investigation

Words: 955 Pages: 3 1847

When it comes to investigating crime, no matter the level of severity, nothing is more valuable to a criminal investigator than the use and implementation of forensic science. The results of such forensic investigations can be the difference between acquittal and conviction in a court of law. The single best aid that forensic scientists use is DNA, which has proven to be a powerful tool in the fight against crime. DNA evidence can identify suspects, convict the guilty, and exonerate […]

Research Paper: Genetically Modified Organisms

Words: 1989 Pages: 7 6214

Genetically modified organisms, otherwise referred to as GMOs, is a highly debated and researched topic throughout the world, however, highly prevalent in the United States today. It is plant, animals, or other organism in which their genetic makeup has been altered or modified by either genetic engineering or transgenic technology. GMOs are used either in the medical field or agriculturally, looking to cure diseases and create vaccines or attempt to get the healthiest or highest profit out a product. Prior […]

About the Cellular Basis of Cancer

Words: 1885 Pages: 6 4506

At a cellular basis, cancer cells are not that different from normal cells. In fact, from a biological view point cancer cells originate from normal cells. The features of a cancer cell; such as migrating away from its origin point, mutating and replicating itself, evading cell death and providing itself with a supply of oxygen and nutrients, can all be found in normal healthy cells (Oppenheimer 2006; Tu 2010). However, it is what these cells then do to the surrounding […]

What is Cisplatin?

Words: 451 Pages: 2 3761

Cisplatin is a "chemotherapeutic agent" that can covalently bind with DNA using the purine base, mainly guanine, in a cross-link that leads to transcription inhibition, cell cycle arrest, and an apoptotic effect27. Cisplatin is responsible for the production of reactive oxygen species28. Absorption of cisplatin into the nuclear DNA binds two adjacent guanines in the same DNA strand, causing an inhibition of DNA synthesis and cell death29. Moreover, programmed cell death or apoptosis has been associated with several anticancer drugs, […]

Cyclic GMP-AMP Synthase

Words: 385 Pages: 1 3823

Genomic DNA can be damaged by endogenous or environmental stresses. During repair, these short single-stranded DNAs are continuously generated and may leak out to the cytoplasm, where they are generally drawn back into the nucleus by DNA repair and replication factors (RPA and Rad51). Alongside this, TREX1, a cytoplasmic exonuclease, is anchored on the outer nuclear membrane to degrade leaking DNAs immediately. This prevents activation of the cGAS/STING pathway against self DNA. Inhibition of any of the above-mentioned proteins leads […]

Potential Cancer Resistance

Words: 296 Pages: 1 4217

Cancer proliferation is characterized by uncontrolled and unregulated cell growth resulting in tumors. In theory, as the size of organism increases there are more cells developing and dividing meaning that this is an increased probability of cancer development. Although, this response is theorized this is not what actually occurs, but why this trend is observed remains poorly understood. The present study aimed to understand these mechanisms of cancer suppression in large, vertebrate mammals in hopes of gaining insight to human […]

Exploring the Intricacies of Genetics through DNA

Words: 1251 Pages: 4 6296

Introduction The hereditary molecule that is tasked with carrying genetic instructions that are used in all living things in development, growth, reproduction and functioning is referred to as deoxyribonucleic acid (DNA). DNA molecules consist of two strands which are bipolar and are mostly coiled near to one another to form a spiral. This strands are referred to as polynucleotides simply because they are made of small units known as nucleotides. The information of the DNA is stored in this nucleotides. […]
