(PAGO PAGO--JANUARY 31, 2016)--The Community and Natural Resources (CNR) division of the American Samoa Community College (ASCC) offers the Territory’s public and private high school students the opportunity to gain an edge in their science studies by participating in Molecules of Life Explorations, a series of weekly two-hour sessions in which students participate in discussions about principles and practice of molecular biology. The sessions precede hands-on lab activities.

A collaborative effort between ASCC-CNR, the American Samoa Department of Education (DoE), Office of Curriculum and Instruction (OCI) Science and Pacific STEP UP, Molecules of Life Explorations offers training to high school juniors and seniors in basic molecular biology methods and life science laboratory techniques that is not otherwise available in American Samoa. It provides a critical introduction to help prepare students for college-level life coursework while giving them a hands-on feel for the biomedical sciences that is essential for advanced studies or even careers in the field.

The program, provided without charge to the students, has been underway since September of 2015 and will continue through May of this year. At total of 96 student applicants, divided into 16 groups of six, spend two hours a week during normal school hours at ASCC-CNR for a total of four weeks per group during a morning or afternoon session. DoE instructors, OCI Specialists and ASCC-CNR staff provide training and supervision. Instruction includes proper safety precautions and techniques for molecular-level analysis of the macromolecules responsible for biological activity—techniques commonly employed in molecular biology labs around the world.

As part of their work, the students extract and amplify regions of their own DNA using the polymerase chain reaction and determine their genotypes using gel electrophoresis. DNA extraction, PCR amplification, and gel electrophoresis are techniques commonly employed in biomedical facilities around the world, including clinical diagnostic labs in hospitals, police forensic labs, and life sciences research labs. This type of training in basic molecular biology methods and life sciences laboratory techniques provides a critical introduction to college-level coursework.

Weekly lectures and discussions are facilitated by Dr. Joserose Jyothibhavan, Science Specialist with DoE-OCI, while hands-on laboratory activities are led by Emily Ilaoa, ASCC Land Grant Plant Pathology Research Assistant. Dr. Joserose and Ms. Ilaoa are assisted by Plant Pathology and Entomology Research Assistants Shalley Tailevai and Metotagivale Meredith. ASCC Land Grant Plant Pathologist Dr. Ndeme Atibalentja provides critical technical backstopping for planning and developing the program activities. Participants were selected from applications submitted by high school juniors and seniors to their science teachers. Requirements included the students having a GPA of 3.5 and above, having completed of Physical Science, Biology, and Algebra 2, and being currently enrolled in Chemistry or Physics and Pre-Calculus or Calculus.

The Molecules of Life Explorations program utilizes the molecular biology laboratory established at ASCC-CNR via the Pacific STEP-UP program. STEP-UP, funded through the U.S. National Institutes of Health, is coordinated in the Pacific by Dr. George Hui at the University of Hawaii John A. Burns School of Medicine.
