Napomena autora:

Students read an article in TheGuardian and answer questions about a mutant enzyme accidently discovered which could eventually help reduce plastic waste by breaking down the plastic into it's original components.

Please read the article found at this URL:

https://www.theguardian.com/environment/2018/apr/16/scientists-accidentally-create-mutant-enzyme-that-eats-plastic-bottles

and answer the questions below. Thanks. Live long and prosper.
