A mutation is a genetic error in the creation of DNA. My science teacher compared it to a copier that made a mistake; the DNA is copied from others, but the "copier" messed up, making part of a helix different. Mutations can be genotypes or phenotypes.
Depending on what resources you use, it can be easy or difficult to get examples of each categories
Some easy way can include searching google, wikipedia, encyclopedia.org, etc. These usually give you a broad and large amount of information that you can draw out of, and an over view that allows you to know what the paragraph would be talking about before you use it.
Difficult ways would be searching through specific websites, such as national geographics, etc, which gives you specific details on the idea (and is more trusted then the others)
Remember too always get facts, not opinions, unless your question asks for others opinions, and to look for what researchers or well-known people within that topic says, and to not get any information from "who-knows-who-typed-it" websites, such as ask.com, etc.
hope this helps
First, scientists isolate the gene that controls insulin production. Then, they take that gene and insert into a plasmid (a circular ring of DNA found in bacteria). When the bacterium with that plasmid reproduces, it carries that insulin-producing gene. Then they can either mass-reproduce that bacteria or transfer the plasmid to another rapidly-reproducing bacteria. After some time, they harvest the insulin from the bacteria.
I believe that would be thermal energy. Collecting energy from underground magma...
