The author explains the basics of DNA by describing the simple part of it, “proteins are the molecules that do all of the work in every organism, from carrying oxygen, to building tissue, to copying DNA for the next generation” (Carroll 73). He also explained the four bases that are building blocks that are held together by strong bonds and are represented by the letters A, C, G and T. Scientist also learned that A and T always pair with each other as well as G and C, this helps them because if they know one strand of DNA they already know the second because of how the bases match up. The author states that scientists have found about 500 genes that exist in all forms of life, the author explains that these genes are “immortal”. These genes have endured millions of years of evolution and have not been mutated because they are essential for every organism to have; these genes can have important jobs such as decoding of the DNA and RNA and making

Biology is a broad field, covering the minute workings of chemical machines inside our cells, to broad theories of ecosystems and global climate change.

Each human being has something called DNA. DNA is described as genetics and an extremely long macromolecule that is the main component of chromosomes and is the material that transfers genetic characteristics in all life forms. DNA constructs of two nucleotide strands coiled around each other in a ladder like arrangement with the sidepieces composed of alternating phosphate and deoxyribose units and the rungs composed of the purine and pyrimidine bases adenine, guanine, cytosine, and thymine. Each chromosome consist of one continuous thread-like molecule of DNA coiled tightly around proteins and contains a portion of the 6,400,000,000 basepairs that make up your DNA.

Moshe Szyf, an epigenist informed us through his Ted Talk, “How life experience is written into DNA,” of our genes and how they are “combined of two components” (15:17). He used rhetorical strategies to engage his audience in understanding the view of DNA through an epigenetics perspective. He provides many examples of experiments performed which show these layers of information. The two layers include the old information from millions of years of evolution and the epigenetic layer which includes the open and dynamic set up of a narrative that is interactive and allows us to control our destiny.

Genetics can help answer questions about our traits and why we look different and advance in different ways from each other in the world. Chapter 1 explains the basics about how genes work, and the portrayal of DNA and RNA. Chapter 2 describes RNA more in detail and it consist of the explanation of the human genome. Specifically, Chapter 3 clarifies how evolution works and how it relates to genetic and medical research. Furthermore, Chapter 4 and 5 explains the knowledge researchers have about genes role in health and diseases, and how society is affected with the advances in medicine and science given approximate credit to these researchers.

I have found studying A –level Biology very intriguing; it has enhanced my knowledge of key biological processes that allow humans to thrive as a species and given me some insight into relevant topics of Biomedical science such as genetics

The observatory sense demonstrated by scientists to eventually conclude that inheritance is more than genes and the DNA sequence is both commendable and insightful. It was surprising to find out that genes are not the only genetic components passed from one generation another. They are not the only one that influences transgenerational changes. More surprising was the revelations that the human genome has more than 30,000 genes that could be switched on and off due to environmental stimuli. Essentially, genes experience epigenetic changes. These chemical labels accrue over time and influence the turning on and off (BBC Channel TV, 2015). The switching on and off of genes causes humans to have different kind of cells. It is notable that the effect of the environment is a major factor in explaining the hereditary patterns and the

The research question of the article Designer DNA by Rachel Berkowitz was how the deoxyribonucleic acid (DNA) portrays a unique sequence of protein for every organism. Biologically, all animals including humans have a unique DNA. The study focuses on how the arrangement of four nucleotide bases determines the DNA sequence. For decades, scientists have altered the DNA of various organisms to manipulate the life of living things. They have inserted genes into algae, yeast cells, and bacteria to produce enzymes that appear in different shapes and structures. The researchers hypothesized that software makes it less tedious for scientists to predict the behaviors of host organisms whose DNA have been manipulated. In reality, the actions

During my studies at Excelsior, I have learned about Biology, like where life comes from and how it has developed over the years. To prove my knowledge of this class, I submitted a paper to my Biology Professor titled “Mastering Biology.” Although there is still a ton to learn it is a starting point to get a grasp

DNA, Deoxyribonucleic Acid, is the basic structure for all life, it is the blueprint, the instruction manual, on how to build a living organism. DNA is made up of four nitrogen bases, adenine, thymine, cytosine, and guanine which are connected by sugar-phosphate bonds. Through a process called Protein Synthesis, the nitrogen bases are the code for the creation of amino acids. Essentially, DNA makes amino acids, amino acids make proteins, proteins make organisms. This process has been taking place for much longer than scientists have been able to document. Those scientists are called geneticists and their field is genetics.

In today’s society biology helps us in many ways, from learning how we are made to finding treatments for diseases to learning about our heredity. For example, DNA is used today to find about our heredity. Its stands for Deoxyribonucleic Acid. DNA contain genetic information that has been passed down by parents onto their children for many generations. It is a unique blueprint that makes us alive and without it we wouldn’t be existing today. DNA is what makes us alive today and it’s our guide to life. Its job is to store genetic information and then pass down to our children and grandchildren. In simplifying the basic of DNA, it creates genes, further on genes make chromosomes which make up a cell in which we gain chromosomes from both parents (23 chromosomes from mom and 23 chromosomes from dad). It has also helped doctors and specialists how to keep individuals eat nutrition’s and stay healthy by preventing causing any danger to their health and fight off diseases that can develop. Today, biologist have come up with many solutions to prevent and reduce diseases that can harm people in the future, Because of biology, it has saved many people lives and also has helped live longer.

All living organisms, from amoebas to humans, have a molecular code called DNA in their cells, which instruct the activities that keep the organism alive. DNA is made up of long, twisted strands of four molecular “letters” (A, T, G, and C), which pair up according to their complementary base pairs, and their order determines how proteins — the vital molecules that perform all the major tasks in our cells — are made. (Refer to Diagram 1 to help sum up the concept.)

One of the fundamental discoveries of the 20th century was that DNA was the genetic code’s physical structure (Watson & Crick, 1953) and, since then, many studies have disclosed the complicated pattern of regulation and expression of genes, which involve RNA synthesis and its subsequent translation into proteins.
