Key Stage 3 DNA Discoveries Key Stage 3 Their conclusions were built on by later scientists, and gradually the understanding of DNA developed. DNA Discoveries Are scientists still researching DNA? Student worksheet Yes! All of the DNA in a human nucleus is called the genome. In What makes you, you? 2003, scientists finished an important project, the Human Genome Project, which deciphered the whole DNA code. The simple answer is DNA. This is a chemical Scientists around the world are using this information to work found in the nucleus of your cells. It is a code out what each section, called a gene, does. We now know the that tells your cells what proteins to make. genes that cause inherited diseases, can clone whole mammals These proteins are what give you your and even build artificial cells by creating new genomes. characteristics such as eye colour, blood group and if you have curly or straight hair.

Levine, MD, was in many ways a shooting star for the University of Pittsburgh. n past years, annual report readers have been greeted on page one with a thoughtful column by Arthur S. Levine, MD, senior vice chancellor for the health sciences and John and Gertrude Petersen Dean of the School of Medicine. However, this year is not a typical year because Dr. Levine will step down from his leadership positions, once his successor arrives in June 2020 (see below). So, in lieu of his column, the annual report leads off with the story of Dr. Levine’s tenure, Iencapsulating quite a journey for him and for the University of Pittsburgh In addition, the report is packed with news emanating from the School of Medicine and the achievements of its students and faculty. All is worthy of reflection. Anticipation n January 7, 2020, Anantha Shekhar, MD, PhD, a nationally recognized educator, researcher, and entrepreneur with major contributions in medicine and life sciences, was named senior vice chancellor for the health sciences and John and Gertrude Petersen Dean of the School of Medicine.
