Can references be plagiarized
Common knowledge does not need to be cited. Common knowledge includes facts that are known by a lot of people and can be found in many sources. For example, you do not need to cite the following:

Abraham Lincoln was the 16th President of the United States.
Sacramento is the capital of California.
A genome is all the DNA in an organism, including its genes.
