In the shadow of the fallen towers, there was more than just rubble and the terror. There were countless chemicals in the air, some good, some bad, and some deadly. Asbestos was among the deadly chemicals. Throughout history and throughout the world, it has been used to meet the need of materials to act as insulators, and much more. It is resistant to heat and corrosive materials, as well as being a very good nonconductor of electricity. Its hollow fibers are what make it a good insulator…

melanogaster, which commonly is known as fruit fly, has been used in genetic study for centuries. They tend to give birth to a large amount of offspring while their life cycles and generations are short. Their genes can be mutated easily by radiation or mutagens in food. They have four large chromosomes with approximately fourteen thousands genes. As expected, human have several times more gene than D. melanogaster, however, we have almost the same number of gene families. And fortunately,…

degrees of mutations. It is expected that mutations occur at a higher rate in cave animals because the slightly deleterious mutations are fixed within the population due to their genome size, the smaller population size and the difference in chemical mutagens found in…

Protein mutations are often introduced at the DNA level in the corresponding gene, which takes advantage of the central dogma of biology (DNA is transcribed to mRNA; mRNA is translated to proteins. The introduction of mutations in target genes has become trivial with the advances in synthetic biology. Major classes of library construction include (1) random mutagenesis, (2) recombination, (3) semi-rational design, and (4) scanning mutagenesis. Together, these classes of library construction…

Smoking can be of tobacco products or marijuana, tobacco is the main product smoked with an estimate of 1 billion smokers in the world today. Smoking has effects to both the smokers and the people living with them and the most common of them is cancer. Smoking has various impacts ranging from health, financial and social. All these impacts are negative since there is no known documented positive effect of smoking Smoking causes various types of cancers namely; tongue, bladder, ovary, lung,…

most because before then the human brain hasn’t developed the blood brain barrier which is in charge of directing contaminated blood out of the brain to lessen the effects of the chemical. Lead is a Neurotoxin, an endocrine disruptor, a teratogen, a mutagen, and a carcinogen. It can have all these affects at once or any combination of them. Lead inhibits the transport of oxygen and which alters nerve transmission in the brain which prevents it from making new synapses. One of America’s first…

800 different compounds (Saha, Bhalla, Whayne, & Gairola, 2017). The chemical compounds in cigarettes contain many different types of gases and toxic properties. Approximately 100 of these compounds are considered carcinogens, cocarcinogens, and mutagens (Saha et al., 2016). The gases associated with a cigarette include formaldehyde, carbon monoxide, ammonia, and a number of other gases (Saha et al., 2016). The chemicals found in cigarettes can potentially lead to negative effect on the oral…

Caroline Hentzen ENLT 2555- Professor Chase Argument Paper In today’s society, there is a diagnosis for every minor issue, whether genuinely medical or not. As Riska argues in her paper “Gendering the Medicalization Thesis,” medicalization becomes an area of social control (Riska 63). Diagnoses of a time period determine which behaviors are socially accepted and which ones are negatively viewed. A defiant child can easily receive a diagnosis for a psychological disorder despite whether it is…

Saibhuvaneswari RA1611014010048 JUMPING GENES Transposable elements (TEs), also known as "jumping genes" or transposons, are sequences of DNA that move (or jump) from one location in the genome to another. A transposable element (TE or transposon) is a DNA sequence that can change its position within a genome, sometimes creating or reversing mutations and altering the cell's genetic identity and genome size. Transposition often results in duplication of the TE. The transposable elements make…

Sodium Azide There is perhaps not a lot known about this chemical and what it can do to/for people. One important aspect is to know what the chemical is made of, doing so will give someone a general look into its makeup. Secondly, “What is something we use this chemical for in everyday life”. Lastly, “How does this affect our cell breathing process?” From these topics, one can gather a general sense of what this substance does and whether or not it should be strayed away from. Of course it…
