DNA

to transfer those genes to a new host. This process is accessible to every species. Genes are also passed on from generation to generation which was referred to in the interview as “Nature’s Evolution.” As a human species, being able to modify our DNA with engineering can increase the complexity…

Genetically modifying organisms sounds scary, especially when consumers find out it is in their food. For many, images of oversized chickens or unnaturally large tomatoes come to mind. This is because many do not know how a GMO is created or what is considered to be a GMO. Claims spew that what is inside genetically modified organisms are cancerous and unknown chemicals are injected into the organism. A common misconception is that any organism outside of society's idea of natural or organic is…

scientific knowledge and technological field. With this increasing knowledge the boundaries have become a thin line as the drive for discovery grows. In an alternate world such as GATTACA, technology dictates the lives of its citizens. From birth to death, DNA samples are taken that inform people of your entire history. With such an intrusive system the boundaries of science are called into question. Advancements today make it possible for such technology to exist however, ethical issues arise…

modified or engineered to improve production and/ or profit of the company. This is done with a certain process that is used to locate and change the genome’s structure. Companies have the ability to change the DNA and biochemistry of organisms to change the way the plant grows and are able to move DNA from multiple sources.…

when in low concentrations, could be mutagenic and carcinogenic but another cause of human exposure to this type of agents is cancer chemotherapy, in which they are choose due to their ability to induce extensive DNA damage and cell death (9). They also can induce a great quantity of DNA lesions because they can react with different…

sequenced by DNA polymerase which requires an RNA primer and DNA template to start forming a new DNA chain. DNA polymerase can only act on the ‘3 end of an unravelling DNA strand, called the leading strand, while the other strand being synthesized is called the lagging strand. The RNA primer initiates the new DNA synthesis by providing a starting site for DNA polymerase to initiate its process. DNA then separates into two strands where it can be replicated into two new chains of DNA. An RNA…

many extinct species, such as dinosaurs and the woolly mammoth, or to change the DNA of an already living species. In order to recreate one of these species, one must have the DNA of the extinct species, an appropriate host animal (one that looks relatively similar to the extinct species), and access to CRISPR, the latest technology for DNA coding. CRISPR uses an enzyme called Cas9 to cut open old DNA and implant new DNA from another person/species. This is all very cheap as well, costing about…

The RNA worlds together with the DNA world are known to have numerous differences as well as similarities with the cell nature as well as the varied virus character demands pointing to the viruses coming first. To a degree, the theories that designate this phenomenon have contended on the dissimilar nature of viruses, as a crucial factor that illustrates the viruses coming first (Woese, 1987). In the biosphere of microbes, whereas viruses are regarded as minuscule in size, the Pithovirus is…

A system of molecules called CRISPR/Cas9 are being used to modify the DNA in adult human cells and animal embryos. CRISPR identifies the target DNA which Cas9 slices the strands (“CRISPR Treats Genetic Disorder”, 2016). According to an article written by Cyranoksi and Reardon (2016), this process could eradicate devastating genetic diseases in humans before birth but it may cross an ethical line. Whether or not it is ethical to edit human embryos is being debated. This process has an…

phenotypical features are conserved in DNA, and then these become expressed through a mutation that either knock out the overriding genes for the new traits or make the old traits override the new one. The Genes do not determine what the organism is, but with atavism, they can sometimes serve as reminders of our evolutionary past. However, there are disadvantages to atavism…
