Molecular biology

It would be an understatement to say that the combination of biology and medicine has merely peaked my interest, considering the profound understanding I have digested from appreciating a diversity of biology textbooks and research publications. Since middle school, I have motivated myself to advance my knowledge of the molecular, cellular, and genetic aspects of biology through both independent study and competitions, as to progress my academic ambitions. Consequently, the amalgam of lectures,…

behavioral circuits. Drosophila melanogaster (fruit flies) are ideal for this type of work because of their well-defined behavioral output and mapped neural circuitry. Fly brains comprise only ~100,000 neurons, and there are abundant genetic and molecular tools…

Module #11 Chapter 21 Books cited: Becker’s world of the cell: J. Hardin, G. Bertoni, and L. Kleinsmith: 8th edition; pgs. 645-646 & 657–659. Question #1 from D2L: What is the central dogma of molecular biology? The central dogma is the explanation of how genetic information flows as it is passed from DNA to RNA to protein. DNA replicates and converts the information it carries into RNA, this process is called transcription. During transcription the information is passed through nucleic…

The textbook, Biology: Life on Earth with Physiology defines natural selection as “unequal survival and reproduction of organisms due to heritable differences in their phenotypes, with the result that better adapted phenotypes become more common in the population” (Audesirk…

When I was in seventh grade I had a biology teacher, Mrs. Greenfelder, that changed my life. My experiences, through her leadership, instilled a love of science. Her passion and knowledge of the subjects was inspiring. She lived the science and made it relative to my everyday life. Soon after, I was driven to a pursue a career in the biology field. After taking some time away from my career to prepare my young children for school, I am excited to pursue my professional goals. I would like…

Genetics is a fascinating field of biology that deals with heredity and shows how the characteristics of living things are controlled by their genes.The Gene Researcher for a Week (GRFAW) program is right for me because I have a strong passion to learn about genetics and contribute to research efforts at a genetics lab. I have developed skills that would make me a good scientist through both my education as well as extra-curricular activities and I am excited to apply these skills to this…

Recent technological advances in biology have prompted me to want to study the subject as an undergraduate. I have been drawn to how the world works and what everything is made up of since secondary school, but in recent months my focus has shifted specifically towards the study of genetics. A wide and varied subject, ranging from eugenics and the ethical considerations of genetically engineering organisms, and to the more recent scientific breakthroughs in said area of study, the study of…

After reading chapter three I had a better understanding of DNA replication, what genes do, and also how humans are connected to other species, a better understanding on how we are all part of a “biological continuum”. In 1962 three men named James Watson, Francis Crick, and Maurice Wilkins won of the most distinguished award which was the Noble prize. Although one more person also help discover DNA which she was not credited was Rosalind Franklen. DNA replication is the process one strand of…

conditions to estimate the molecular weight of proteins within a sample. The protein sample was from the previous using anionic exchange chromatography to partially purify N-acetyl--D-hexosaminidase, Lab 3. The molecular weight was determined through the interpolation of a standard curve of proteins with a known molecular weight. The molecular weight of band 1 was determined to be 67,640 daltons and band 2 was 44,420 daltons, disproving the hypothesis that the molecular weight of the unknown…

My intended STEM major that I choose to study in college is biology. I choose to major in biology because I found it fun and interesting and also because it is something that I needed to have a good understanding of if I plan to have a career in the medical field. I wanted to major in biology because I enjoyed biology in my sophomore year and it was one of the few classes that I was excited about. Although it's going to be harder and more complex in college,it will interesting and a new…
