The College of Medicine of the University of the USA - Texas offers a double degree program on medicine and molecular biology. Once you complete the requirements of the said program, you will graduate as a Medical Doctor and a Doctor Philosophy in molecular medicine (MD- PhD).
Once of the requirements of the said program is to publish a dissertion on molecular medicine. Suppose you are on your final year under the said program, you will discuss one biomelecular disorder. You will then propose possible ways on addressing the said disorder.
Do you agree with the statement “Almost all aspects of life are engineered at the molecular level, and without understanding molecules we can only have a very sketchy understanding of life itself.”Justify and support your answer using the important concepts learned from the module. What do you think is the future direction of all countries towards addressing SDG 3 using nanotechnology and or genetic engineering? Cite one (1) example of an emerging practice or application for guided and evidenced based decision- making that uses advanced techniques and equipment.

In 2003, as a result of the Human Genome Project, the complete sequence of all the bases in human DNA was released to the public. Although knowing the entire sequence of bases has proven valuable, scientists are currently working to map genes. Mapping genes involves determining the exact location of each gene. Since much of human DNA does not code for a protein, it is challenging to figure out which segments are actual genes. Often, scientists look at the percent composition of bases in a segment of DNA. If the segment of DNA has a large percentage of C and G bases (together over 50%), it is likely that it is a gene and codes for a protein. 9. A scientist analyzed the bases in a segment of DNA from a human skin cell to determine if it codes for a protein. The base A (Adenine) is 11% of the bases in this segment of DNA. Calculate the percentage of bases that would be C…arrow_forward

Scott Kelly spent a year in space (March 2015 to March 2016) aboard the International Space Station, and has spent a total of 520 days in space during his career, as opposed to a total of 54 days in space for his brother Mark. One of the ongoing investigations was the study of how space travel influences chemical changes in DNA and RNA. The researchers found that “although 93% of (Scott’s) genes’ expression returned to normal postflight, a subset of several hundred ‘space genes’ were still disrupted after return to Earth”. (A) Many mainstream media outlets reported this incorrectly by stating that Scott Kelly's genome was now only 93% identical to his brother's.
