Cell Biologist Research Paper

1. An understanding of chemistry is important for an understanding of biology because biology needs the models of chemistry to better describe life.

Biology 102 introduces students to the concept of evolution, the principles of evolution, natural selection, and major kingdoms of living things organisms. My major is nursing and taking this course is a prerequisite and is required for my major. Taking Biology courses will help me be better knowledgeable in my chosen field. I took biology 101 last semester and we learned about cell and organisms. These are fundamentals things that someone who plans to have a career in the healthcare field needs to know. Also these courses are prerequisites for other science courses I have to take such as microbiology, human anatomy and physiology. As a future nurse these are information that will come in handy everyday. I have three years left in my undergraduate study and more

This paper explores the history and some interesting facts about DNA. The last couple centuries have seen an exponential growth in our knowledge of DNA. The history of the DNA can be traced back to multiple devoted scientist. This article attempts to summarize, and review the basic history of DNA while providing some fascinating information about it.

George Gey was the head of tissue culture at Hopkins and was determined to grow the first immortal human cells. Researchers in 1943 proved an immortal

In the early 1950s, the race to find the structure of DNA was in full swing. The search was being conducted at three different colleges. At the California Institute of Technology, Linus Pauling,

Earth’s vegetation and animal life are all part of an intricate “web” of essential relations in which both cannot survive without the other. According to Campbell’s Biology textbook, The transfer of food energy up the trophic levels is referred to as a food chain. This chain usually begins with plants, (primary producers), then herbivores, (primary consumers), to carnivores (secondary, tertiary and quaternary consumers), and finally decomposers. When one part of the chain is low in population, the species above it are likely to be negatively affected and will likely drop in population as well. In order to show how delicate this web is, and how human activity has affected this system, Carson describes a small food chain in which sagebrush

15. Which three classes of lymphocytes are the primary cells of the lymphoid system? What are the functions of each class?

The major thing that Carol W. Greider discovered was the enzyme telomerase. This Organelle is what scientists believe that controls the

Inorganic phosphate (Pi) is a key nutrient for plants and it is involved in a myriad of metabolic processes and functions that allow their growth and development. Since it is such an important nutrient its uptake, transport, storage and usage are tightly regulated. Never the less the reduced availability of Pi in the ground is a mayor limiting factor. When phosphate starvation occurs the plant has to adapt to survive. Such stress triggers a distinct phenotype in the root such as an increase in root hair length and density, as well as an increase in the ratio root/shoot and proliferation of lateral roots. The changes in root architecture are also accompanied by changes in metabolic processes such as photosynthesis, glycolysis, carbon fixation,

Professor Elizabeth Helen Blackburn is an Australian/American biological researcher who studies telomeres, a structure at the end of chromosomes that protects the chromosomes. She was born on the 26th of November 1948 in Hobart, Tasmania. She is 66 years old and is currently a researcher at the University of California, San Francisco.

Suppose humans could live forever? Some of us would say we don’t want to live forever. However, most of us given the chance would like to live longer then the current life expectancy which is about 80 years especially if we are healthy. This paper explores the idea that humans could up to 1500 years old by understanding telomeres and the enzyme telomerase and their effect on aging. Telomeres are the tip ends of DNA strands of chromosomes their role is to keep the DNA strands from sticking to each other. Every time the cell divides, the telomeres get shorter and shorter as a consequence when they get to short they die or go into a senescent state. There is a limit to how many times a cell can divide before it reaches that state if not for the

Carol W. Greider discovered the enzyme telomerase, which is how chromosomes can be copied in a complete way during cell divisions. She discovered this while being a graduate student in Berkeley, along with her partner Blackburn and Jack W. Szostak. Her father was a physics professor, and she is dyslexic. Yet, she managed to make a great discovery and even show people that women can be in the scientific field as well. Her discovery has helped many scientists, and thanks to her and her partner, we have been able to use it for many uses. The story is Carol W. Greider is quite an interesting one. She had definitely been through a lot to get to where she was. She was born in April 15, 1961, San Diego , CA, USA. She was dyslexic, and her mother
