genetic mutations and influence
n-text citation: This is a concept that eludes most people.
If you are using an idea that is not common knowledge you need to provide a in-text citation (see style guide and assignment).
When you are paraphrasing one of your sources, you need to cite.
When you quote, you need to cite. When in doubt, cite. Not citing is called plagiarism.
I will not deduct too heavily for the exact lack of citations, having a paper without any will have a negative effect on your grade.
Frequently asked questions about sources:
Once I have my academic sources can I use other non-academic ones? - Yes, you may.
But do not lean to heavily on them for the content of your paper or your grade will suffer.
Can I use our book, or lecture? - Yes, but same as above, do not make them your primary sources.
