DNA: What is Yours Worth?

Words: 2389 Pages: 8 5672

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 […]

The Building Blocks of Life: Understanding Cells and Their Impact

Words: 1006 Pages: 3 7659

Cells are the fundamental units of life, forming the intricate makeup of all living organisms. In every organism, cells fall into two primary classifications: prokaryotes and eukaryotes. Prokaryotic cells, which are typically single-celled organisms, include bacteria as a prime example. In contrast, eukaryotic cells make up multicellular organisms, with humans being a notable example. The human body is composed of an astounding 75 trillion cells, each serving a distinct purpose and function, contributing to the remarkable complexity of human anatomy. […]

DNA Structure and Mitosis

Words: 601 Pages: 2 6089

Cellular division through mitosis and meiosis ensures the continuity of life across generations. These biological phenomena are responsible for cell reproduction, growth, and genetic diversity. While both processes involve the division of cells, they serve distinct purposes and have unique characteristics. Mitosis is primarily concerned with growth, repair, and asexual reproduction, whereas meiosis is essential for sexual reproduction and genetic variation. This essay aims to compare and contrast these two critical processes, highlighting their phases, outcomes, and significance in the […]

Forensic Science: Bridging Law and Science

Words: 806 Pages: 3 4051

Forensic science, at its core, represents the intersection of scientific principles and the law, providing crucial support in the pursuit of justice. Its application is essential in unraveling the complexities of criminal cases, where it serves as a bridge between scientific inquiry and legal processes. The various branches of forensic science—ranging from entomology and pathology to criminalistics and computing—demonstrate its breadth and relevance in modern society (Dominick et al., 2009). This essay explores the evolution of forensic science, focusing on […]

The Role of Forensic Science in the Criminal Investigation

Words: 955 Pages: 3 3926

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 […]

About The Cellular Basis of Cancer

Words: 1885 Pages: 6 6131

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 […]

Cyclic GMP-AMP Synthase

Words: 385 Pages: 1 5546

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 5893

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 […]

Eukaryotic Cells: The Intricacies of Nucleus Dynamics

Words: 633 2308

Eukaryotic cells, ranging from towering redwoods to minuscule algae, owe their complexity to a fundamental feature that distinguishes them from simpler organisms: the nucleus. Enclosed within a double membrane called the nuclear envelope, the nucleus houses the genetic blueprint of the cell in the form of chromosomes. These DNA-packed structures not only dictate an organism's physical traits but also play a pivotal role in its adaptability and survival. Far from being a static repository of genetic material, the nucleus is […]

The Essential Phases of a Cell Cycle

Words: 433 Pages: 1 2433

The cell cycle is like a well-choreographed dance that all living things must master. It's how cells grow fix themselves up and make sure everything stays in balance. This cycle has four main acts: G1 S G2 and M phase each with its own job and ways to keep everything running smoothly. First up is G1 the growth phase where cells beef up before they start copying their DNA. They stock up on all the goodies they need and check […]

Deciphering the Genetic Code: The Fascinating Story of DNA

Words: 598 2523

From the earliest days of biological inquiry to the cutting-edge research of today, DNA—Deoxyribonucleic Acid—has captivated scientists and enthusiasts alike. At its core, DNA serves as the molecular blueprint for all living organisms, carrying the intricate instructions necessary for growth, development, and reproduction.
