Who is Aziz Sancar?
Aziz Sancar was born on September 8, 1946, in Savur, a small town in the Mardin province of Turkey. Coming from a modest background, he was the seventh of eight children in a family that placed great emphasis on education. Despite limited resources, Sancar excelled in his studies, particularly in science and mathematics.
He pursued his undergraduate degree in medicine at Istanbul University, where he developed a strong interest in biochemistry and molecular biology. Later, he moved to the United States to further his studies, eventually earning a Ph.D. in molecular biology from the University of Texas at Dallas in 1977. His doctoral research focused on DNA repair mechanisms in bacteria, a topic that would define much of his scientific career.

What are Aziz Sancar’s Major Contributions to Science?
Aziz Sancar’s most significant work revolves around the mechanisms that cells use to repair damaged DNA. His research has had a profound impact on medical and biological sciences. Some of his major contributions include:
- Nucleotide Excision Repair (NER): Sancar discovered how cells remove damaged DNA segments and replace them with correct sequences. This process is crucial in preventing mutations that can lead to cancer.
- Circadian Clock and DNA Repair: He studied the relationship between the body’s internal biological clock and DNA repair, providing insights into how cancer treatments can be optimized.
- Photolyase and Light-Activated DNA Repair: His early research demonstrated how cells use light to repair UV-induced DNA damage, a process known as photoreactivation.
These discoveries have led to advancements in cancer research, particularly in understanding how cells respond to radiation and chemotherapy.
