Conjunctions .

The coordinating conjunctions are: for, and, nor, but, or, yet, so.

Three subordinating conjunctions are 'after,' 'when,' and 'even though.' For a list of common subordinating conjunctions, visit this site: http://englishplus.com/grammar/00000377.htm

"Do" is not a conjunction. It is a verb that indicates action or a state of being. Conjunctions are words used to connect words, phrases, clauses, or sentences, such as "and," "but," and "or."

No. After the word and comma can not be used, as it is grammatically inappropriate to use comma after conjunctions such as and, which are called coordinate conjunctions.
