Gene is a basic physical and functional unit of heredity and is made up of DNA. It occupies a fixed position on a chromosomes, which are the sets of genes in the body. They determine how a body forms and functions during pregnancy and after …

The Genographic Project I. INTRODUCTION A. (attention grabber): Everyone here probably knows what ethnicity you are, where your immediate family came from, or maybe can even trace your great-great grandparents. But what if I told you that you can find out where your ancestors came …

Humans are engaged in a “micro-war” with bacteria, and we are losing.  Bacteria represent one of the most adaptable organisms on the planet primarily due to their propensity for adopting genetic mutations. (more…)

Arthur Kornberg was born on March 3, 1918 in Brooklyn, New York. He was educated in Abraham Lincoln High School and continued his education at the City College of New York. This was where he first received his scientific training as he graduated with a …

Mutations are various forms of changes in ones DNA’s structure or makeup. This abnormality can happen for various reasons such as chemical misuse, harmful viruses or environment factors. When a mutation occurs in ones genetic structure, there is often a push to find out what …

4 Sub-Fields: Socio-Cultural – focuses on living human cultures, global patterns of belief and behavior found in modern and historical cultures, participant observation a. Influenced behaviors, customs, traditions, beliefs b. Non-biological of adaptation to the human environment, social and natural Anthropological Linguistics – description and …

On one side of the world, in the middle of nowhere, a potentially beautiful child is just skin and bones; on the other side, another animal that can not be replaced has gone extinct. Somewhere there is a woman washing her few belongings in a …

Despite many issues of reliability of LCN analysis, this technique is already well established. The question in validity of LCN typing lies not with the technique itself but how DNA is handled to avoid contamination. Several methods have been reinforced in order to increase reliability …

The Island of Dr. Moreau ( 1996 Film )For this assignment I have chosen to discourse the movie “The Island of Dr. Moreau” . This movie was released in 1996 based on H.G. Wells’ novel. After acquiring past the horrific and ghastly scenes and cliff-hanging …

The research paper of Hindley and colleagues (2007) describes the function of the protein transportin in the entry of adenovirus-associated proteins in a cell.  Adenoviruses are microbial organisms that contain genetic material that has been highly compacted by the help of adenoviral core proteins. (more…)

Recombination is a way in which meiosis produces new combinations of genetic information. During synapsis, chromatids may exchange parts with other chromatids, leading to a physical exchange of chromosome parts; thus, genes from both parents may be combined on the same chromosome, creating a new …

Introduction The deoxyribonucleic acid (DNA) its an organic compound whose molecules contain genetic instructions, its role is to store necessary information to create ribonucleic acid (RNA) and proteins. The DNA segment that encloses this information is called a gene. The DNA molecular structure was discovered …

What was the most significant conclusion that Gregor Mendel drew from his experiments with pea plants? A) There is considerable genetic variation in garden peas. B) Traits are inherited in discrete units, and are not the results of “blending. ” C) Recessive genes occur more …

If these genes mutate, then one is considered as having a hereditary risk of breast and ovarian cancer. The BRCAI and BRCA2 mutation means that a woman has an increased risk of breast and/or ovarian cancer before menopause. Sometimes close family members were diagnosed with …

Exam 1 Introduction to Anatomy  What is the definition of anatomy? What is the definition of physiology? What is homeostasis? What are the two ways in which homeostasis is maintained? What are the directional terms used to find things in the body? For example, what …

When we consider the universe within us, the molecular intricacies that drive life’s various processes, the sheer complexity and wonder can be almost overwhelming. One of the most fundamental processes at the core of life as we know it is DNA replication – the precise …

Introduction Each individual is marked by unique genetic sequences embedded in strands of DNA (deoxyribonucleic acid), except for identical twins. Surprisingly, DNA source can easily be obtained from single white blood cell, cheek epithelial cell contained in the saliva on cigarette butt or chewing gum, …

Soon of existing cells. Janet Plow demonstrated that the cell membrane is a physical structure, not an interface between two liquids. Lynn Amaryllis proposed the idea that certain organelles were once free living themselves. Cell Theory: All living things are composed of cells. Cells are …

Concocting a Divisive TheoryThe phenomenal recovery of an mtDNA section from the arm of the Feldhofer Cave Neandertal was greeted with the enthusiasm and yes, even with the ballyhoo it deserved. 1 It was a truly important discovery, and from a research lab that every …

Anatomy and Physiology Introduction to the Human body Introduction The human body is such an interesting machine, the way it is structured and how it works is educational. There is so much to learn about the human body and up until today scientists are still …

Bacterial cells are a common choice for in vivo replication of DNA of interest, and in this study, the heat shock method was employed for bacterial transformation. Plasmids, which are DNA molecules themselves, were used as expression vectors for the DNA of interest, the GAP …

The grave environmental issue at hand in this project is the estimated radiation emissions for 10,000 to 1 million years in the future. The Environmental protection Agency in August 9, 2005 had proposed a limit of 350 millirem yearly. Several agencies had continuously supported the …

When populations start to die there are only so many to choose from for genes. A founder effect will then be created (Welsch 73). The Human Genome Project set out to identify all the genetic material in humans (Welsch 265). Another type of variation is …

Long stands of double helical DNA can fit into the nucleus of a single cell because DNA is specially packaged through a series of compaction events to fit easily within cell nuclei. Even though the length of DNA per cell is about 100,000 times as …
