DNA sequence

The Y chromosome also has several microsatellite sequences on it, what makes these microsatellite sequences special is that these sequences locate on the non-recombining region, meaning that they are likely to be preserved along the time. Therefore, it is possible to use these microsatellite sequences to generate a phylogenetic tree for Y chromosome, and researchers did that in 2002: by using the polymorphism mutations exist…

possible genotype-phenotype correlation for WS. Their secondary aim was to provide a possible predicative molecular genetic screening for WS families. The materials and methods consisted of a DNA extraction from peripheral blood samples. These were amplified using PCR in order to sequence the WFS1 gene on an automated DNA sequencer. They established an amplification refractory mutation system, having two complementary reactions using three primers in each and then conducted a comparative genomic…

normal and cancer cell. ○ Explain the process of microarray In a microarray the mRNA is removed from both the infected and uninfected cell. The mRNA is converted into Complementary DNA (cDNA), which is mixed with chemicals. From there cDNA matches up to the DNA already on the slide by looking at the order of the sequence and uniting the two complementary segments. The color on the slide changes depending on… ○ How are the results from a microarray interpreted? ○ Explain how microarray uses Gene…

As species have differentiated over the years, the DNA classification in their genes obtain minimal changes. Because the DNA sequences determine a portions amino acid sequence, a gene that is shared by two closely related organisms should have a similar, or even identical amino acid sequence. The major link form of the protein encoded by the gene is 715 amino acids long and the protein is identical, with no differences…

Evolution is factual despite the great amount of people who don’t believe in the recent discoveries. There are numerous facts supporting Darwinian evolution, in which, Scientists today are finding species splitting in two, observing natural selection changing animals and plants before our eyes, and discovering more and more fossils capturing change in the past-dinosaurs that have sprouted feathers, fish that have grown limbs. Jerry Coyne eloquently shows that evolution does not destroy the…

unethical and could even destroy still-living species’ habitats. Scientists have recently been able to place DNA from frozen woolly mammoths into elephants, their closest living relatives. This process gives the offspring characteristics of both species, including more hair and longer tusks. Another method scientists are using is to cut DNA from the mammoth cells and place it into specific sequences of DNA in elephant cells, which has the same effect as the first method. Both approaches have…

The other disadvantages would be highly concentrated on the biological issues; this is because many problems could occur that are unnatural such as mutations. Mutations are a permanent change in the sequence of DNA that usually cause harmful effects to the physical body; for the animal being tested this is caused by foreign chemicals of the drug that cause mutations. When this happens the mutation causes changes to the chromosomes which makes the physical…

Gene modification is the process of altering the DNA of a living organism such as humans. CRISPR-cas 9 is a genome editing tool where scientist and doctors remove, add, or alter sections of the DNA sequence. It has the capability to treat chronic diseases, create designer babies, and improve the quality of life. Therefore, doctors should be allowed to perform gene modifications on humans. According to Centers for Disease Control and Prevention, in 2012 “one hundred and seventeen million people…

2.5. Morphological Identification/Evaluations of Entomopathogenic Fungi The six isolates of fungal entomopathogens were provided by Department of Entomology, Penn State USA. Preliminary morphological identifications of fungal entomopathogens such as color of colony, mycelial characteristics and spores from all six isolates were done at microscopic level. 2.6. Molecular Characterizations of Entomopathogenic Fungi Cultures of Metarhizium fungus were grown in nutrient broth (Bacto, Australia) in…
