Drosophila: Fruit Fly Lab

The history of fruit flies is considered a tradition. Research of these flies initially entered labs 100 years ago. Thomas Hunt Morgan, who lived from 1866 to 1945, was the founder of drosophila genetics. Thomas preformed his research in Morgan lab at the Columbia University in 1910. Here was when they found a famous mutation,… View Article

10. Errors and Redesign. Throughout this experiment a number of random and procedural errors were apparent; these errors could have affected the results of the experiment in a number of ways. One experimental error that occurred during the experiment was that some flies became stuck in the food source and died. The main cause of… View Article

OCR F215 Biology notes

1. Free RNA nucleotides are activated, two extra phosphoryl groups are added to make ATP, GTP, CTP and UTP. 2. The gene to be transcribed unwinds and unzips. To do this the length of DNA that makes up the gene dips into the nucleolus & the hydrogen bonds between the nucleotide bases break. 3. Activated… View Article

Mitosis lab

Abstract –For this lab there is no experiment to be done only questions to be answered. In this experiment we will categorize and count the cells to compute the mitotic index of the total root area. Introduction – The purpose of this experiment is to answer questions associated with the onion root tip photos that… View Article

Compare and Contrast the Processes of Mitosis and Meiosis.

Many living organisms in the Earth can continue because of the process of producing individuals called reproduction. Both mitosis and meiosis which are nuclear division in mitotic and meiotic cell division respectively play important roles in reproduction. In this essay, the processes of mitosis and meiosis are going to be compared, and the roles and… View Article

Memo – Investment Recommendation for Centagenetix

After looking over the material regarding Centagenetix, I have a recommendation as to whether or not MPM should invest in Centagenetix. I realize that we have spent a great deal of time and resources on this project already, and that Harvard Medical School is anticipating that this deal will go forward. I also realize that… View Article

Differences Between Mitosis and Meiosis

Differences Between Meiosis and Mitosis Mitosis is a word from biology that means cell division. Another word, Meiosis, also comes from biology and means cell division. Cell is the basic unit and building block of all organisms. Cells have to divide because outside of the cell unable to keep up with the inside when the… View Article

Mitosis and Meiosis

Abstract: There are two types of nuclear division, mitosis and meiosis. Mitosis is usually used for the growth and replacement of somotaic cells, while meiosis produces the gametes or spores used in an organism’s reproduction. Hypothesis: Mitosis occurs in whitefish blastula and onion root tip, and it is easily observable. Meiosis and crossing over occurs… View Article
