Sequenced genomes

The benefits and risks of the scientific method of genetically modifying crop species Since the emergence of agriculture over 10,000 years ago, humans have been altering the genomes of the crops they produce in order to increase the crop quality in many ways, with fruit size and palatability being two obvious examples. Whether this occurred incidentally through the techniques used to cultivate the plants or intentionally through artificial selection, humans have created strains of domesticated…

DNA analysis, also known as DNA profiling, testing, typing, is a process that takes genetic material and evaluates it so that it can identify individuals in a criminal investigation or in use of a forensic application. The beginning step of the performance of DNA analysis on a reference sample or person is the collection of DNA from cells. These cells can come from a blood sample or even swabbing the inside of an individual’s cheek. After it is collected, the samples are then sent to a lab for…

In particular, we are interested in understanding the PER gene in relationship to the free running period and the onset of activity in an organism. In addition, we will look to explain how multiple PER homologs arose in the human genome by identifying duplication events throughout…

These vectors contain a 4.7 kilobase DNA genome, and they are created by inserting the desired gene along with promoters and helper genes into the virus where the viral DNA would normally be found. Once the AAV reaches a target cell, the virus synthesizes a second strand of DNA to be paired with…

In the 1920s, A British researchers named Frederick Griffith studied bacterial pneumonia to find a vaccine for it. The specific bacteria was Streptococcus pneumoniae. Using streaking on a cultured Petri dish, the batterie was seperated into two strains, or colonies. The R-Strain was rough, and when injector into mice, it did not cause pneumonia, but the S-strain was smooth and slimy, and caused lethal pneumonia when injected. When the S-Strain was killed by heat, it did not cause sickness, but…

traits, gender, and abilities of their child. This kind of research is currently underway and is known as the Human Genome Project. The goal of the Human Genome Project is to understand each individual gene in the human body that makes a person unique and, in time, be able to allow parents to choose if their child is a boy or girl, if it has blue or brown eyes, etc. (The Human Genome Project). Is it right to be able to choose something that will decide the fate of someone besides yourself?…

these single gene mutations that are lethal, extremely dangerous, or unbearable to the human race. Harlequin ichthyosis, cystic fibrosis and Smith-Lemli-Opitz syndrome are all caused by single genes and can potentially be edited out of the human genome. Harlequin ichthyosis (HI) is a dangerous condition that is predominantly characterized by abnormal skin. Children with HI are born with very thick, hard skin that forms diamond patterns on the body. Between these diamonds of thick skin there…

Biology plays quite a lot on personality, people can be more likely to develop certain personality traits because they inherited them genetically. That is what biological psychologist’s study’s. There is an entire field of science called epigenetics that is all about how changes in behavior due to experience can affect people on a biological level and cause changes in genetics across generations. It’s far from the only thing that influences personality but it plays the part. Heredity plays a…

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…

It is well known that plants contain an abundant source of medicinal properties. It has been estimated that between 25-50% of current prescription pharmaceutical drugs available are derived either directly or through semi-synthetic modifications of natural occurring substances aka the use of bioactive molecules. 
 Stated in the Cancer Therapy ; Fabricant and Farnsworth (2001), reported that 80% of 122 plant derived drugs were related to their original ethnopharmacological purposes.
Dsicussed in…
