DNA is made up of nucleotides. Each nucleotide has three different parts, a phosphate group, deoxyribose and a base. The bases contained in DNA are Adenine, Guanine, Cytosine and Thymine. Adenine is always paired with Thymine, Cytosine is always paired with Guanine. The base pairing is what makes the DNA able to be replicated. The following are pictures of what happens during replication.
John Edward Sulston was born on March 27, 1942. After he graduated in 1963, he joined the Chemistry Department in Cambridge. He gained his PhD degree for research in nucleotide chemistry. Nucleotides are molecules that make up the structural units of RNA and DNA. After this, he devoted his scientific life to the study of molecular biology. He spent a lot of time contributing to the human genome project. Human Genome focuses on the chemical base pairs that make up DNA. The Human Genome Project, was an attempt to sequence all human DNA-is essentially complete. The project was done in 2000. He was a joint winner of the 2002 Nobel Prize in Physiology or Medicine. He is also, currently Chair of the Institute for Science, Ethics and Innovation at the University of Manchester. He is most famous for finding out how cells in C. elegans divide. http://en.wikipedia.org/wiki/John_Sulston
To do this lab you will ned the following items:
First you will need to fill one beaker with bromothymol blue and heat it in the microwave for four minutes. Fill the second beaker with bromothymol blue and put ice in the beaker. The third beaker should be filled with bromthymol blue, at room temperature. After all of the beakers are filled with bromthymol blue, put the elodea plant in each beaker. Sit the beakers under the U.V. light and observe what happens after ten minutes.
