... The analysis consists of four questions: #1 is a cell count; #2 is a comparison; #3 leads students through a calculation of the transformation efficiency; and #4 is open ended and asks students to discuss factors influencing transformation efficiency. Lab 6b is called "Restriction Enzyme Cleavage of DNA and Electrophoresis." Students are told to conduct

From page 58...
... The IB program requires that 25 percent of the teaching hours "be spent following an internally assessed scheme of practical/investigative work, related to all aspects of the program including the options." The subject and design of the labs are at the teacher's discretion. These are used to create a portfolio and must be written using a specified format.

... The examiner moderates the overall practical scheme of work experienced by the students and provides feedback to teachers and schools on their compliance with the IBO internal assessment requirements. Portfolios from individual students are sampled by the examiners to enhance standardization of grades across the program.
