Why might scientists be interested in using algae for biofuel production?

Algae actively absorb carbon dioxide, and therefore reduce the greenhouse effect. Fuel from microalgae is called third-generation biofuel, and development for its production is currently underway. With sufficient information on the composition of biofuels, researchers can significantly improve production processes.

Explanation:

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

not sure if this what   you'r looking for would be percent composition
