Introduction

The Center for Excellence in Education (CEE) was founded in 1983 with the intention of nurturing careers of excellence and leadership in science and technology in young scholars as an essential investment into America's global future. CEE's programs help keep the US competitive in science and technology, furthering international collaboration among leaders of the world. CEE challenges students and assists them on a long-term basis to become the creators, inventors, scientists, and leaders of the 21st century.

 
The USA Biolympiad (USABO) enriches the life science education of nearly 11,000 talented students annually. USABO concentrates on stimulating young scholars' intellectual curiosity and developing their critical thinking in laboratory skills and biological reasoning to propel them to careers of excellence and leadership in science and technology. It provides students with the motivation, curricular resources, and skills training to take them beyond their classroom experience to the level of international competitiveness.

Sample Problems

1. Suppose radioactive thymine was added to an actively dividing culture of E. coli bacteria. What would happen if a cell replicated once in the presence of this radioactive base?

  • Only one daughter cell would have radioactive DNA
  • Neither of the two daughter cells would be radioactive
  • All four DNA bases would be radioactive
  • Radioactive thymine would pair with nonradioactive guanine
  • DNA in both daughter cells would be radioactive

Answer: E

2. If radioactive sulfur (35S) is used in the culture medium of bacteria that harbor bacteriophage viruses, it will later appear in:

  • Bacterial RNA
  • Bacterial cell wallsBacterial cell walls
  • Bacterial cell walls
  • Viral RNA
  • Viral coats

Answer: E
