Genetic code

Charles Darwin was a prolific and monumental figure in biology and modern science as a whole. Through his theory of evolution most of the current knowledge of biology is derived. Throughout the chapters X, XI, XII, and XIV of The Origin of Species Darwin argues that there is a mechanism that drives an evolution of species and that species inherently transform and mutate over long periods of time. Darwin argues that species have mechanisms and methods that modify them over long periods of time…

Epigenetics in my life Michel Martinez Morales Miami Dade College Epigenetics In 1939, Waddington created a new word; epigenetics, as the link between two disciplines: developmental biology and genetics. Epigenetic studies how genes switch on and off during the development of the human being and through the lifespan, how gene activities segregate during cell division and how our progeny can inherit the consequences of our lifestyle (Holliday, 2006). To explain the concept of epigenetics, I…

Richard Dawkins is trying to argue that reality can be proven by scientific evidence and magic is used when we do not know why something happen the way they do. We classify something as real when proven by our five senses. However, “we are able to develop new technology and extend the reach of our senses. For example, a microscope to prove that bacteria does exist”. Although, we cannot see microbes with our naked eyes we can use an instrument to see it. Dawkins only believes in poetic magic,…

Natural selection is a change in organism over time that results in the rise of a new species. Natural selection drives the evolution of species by picking the ones that possibly have better benefits and can survive better. An example that shows how natural drives the evolution of species is the beetles. The beetles have two different colors that they can inherit from their parents. They can be in the color green or brown. The beetles will get eaten by crows depending on the environment they are…

“Brave New World.” The themes that are most technology based that I see include: Science as a means of control - Technology and science are used from the beginning with the test tubes and determining the intelligence of each person. The threat of genetic engineering – Manipulating DNA is a technological advancement and was done when the new world bred prescribed…

Cri Du Chat Syndrome Section 1 The genetic disorder Cri Du Chat stems from the deletion of a portion the p arm of chromosome 5 in the affected person. This deletion is seemingly spontaneous in most affected individuals. “Approximately 90% of cases results from a sporadic, or randomly-occurring, de novo deletion” (6. pg. 606). This deletion may include a fraction to the entire loss of the p arm of the fifth chromosome as a whole. Taking into consideration the very spontaneous nature of…

The first step in phage infection is the attachment of the phage to the host cell surface. This is typically accomplished by the recognition of a receptor on the outside of the bacterial cell wall such as an antigen, pilus or other structure. There is much variability from phage to phage in terms of which receptor they bind to. Bacteriophage can generally be classified into two categories, lysogenic and lytic (virulent) (Fig 6). The choice between the lytic and lysogenic cycle depends on the…

The question that gets a lot of people worked up is, Is evolution real? Although many people have their arguments on whether or not it is, this paper is going to be about the actual scientific facts proven about evolution. Evolution, despite what some may believe to be true, is the process in which living organisms have changed and developed ”evolved” into different species, but are believed to have derived or originated from a single species or ancestral background (Biological Def.). This can…

Summary/Response: “Human Reproductive Cloning: A Conflict of Liberties.” In this article “Human Reproductive Cloning: A Conflict of Liberties,” Joyce C. Havstad’s conflict is if cloning becomes safe and reliable, people should be able to have reproductive freedom. The author explained that promoters of human cloning know that it may lead to harmful characteristics. Instead of positively promoting human cloning they explain the causes and effects that could take place. They do strive to allow…

Today, DNA profiling is well used all over the world. DNA profiling was developed by the geneticist of the Leicester University in 1985. DNA profiling is the process where a specific DNA pattern, called a profile, is obtained from a person or sample of bodily tissue (“DNA profiling Biotech Learning Hub”). By learning DNA profiling, it enable us to identify individuals. It is really common to use DNA profiling now and a lot of people starts to use the technology. While supporters of using DNA…
