A comma is not strong enough to perform such actions. In this case you would use a semicolon; when you use a semicolon the thought isn't finished but is broken up so it's easier to read and understand.
DON'T: Use a Period Too Soon
When you form a sentence you want to make sure there is a noun and a verb. For example: "The brown dog." What did it do? The period was used too soon and there is no action. This makes it a fragment rather than a sentence. In the sentence "The brown dog chased the ball," there is a noun and a verb, which form a complete sentence that ends with a period.
DON'T: Use Every Punctuation Mark in One Sentence
When you use too many punctuation marks in one sentence the reader can lose track of your thought. That can be not only frustrating to the reader but can lead to misinterpretation of what you are trying to say. If you are at a point where you have four or more different punctuation marks in the same sentence, it may be time to reevaluate the structure to see if you can make it read better. Splitting your thought into two sentences may be a better solution.
To use basic punctuation properly you must know the rules regarding what each punctuation mark does.When you use the wrong punctuation mark or place the correct punctuation in the incorrect location reading can be difficult and your point may not be made. When reading becomes difficult it's hard to keep the reader's attention and your point doesn't get across. Using these basic punctuation rules will help with research paper for you and ensure your readers focus on your thoughts and ideas rather than trying to figure out what you mean.
