In this sentence, we need to make sure to add the appropriate punctuation marks. The sentence states a fact, so we should put a full stop at the end. Also, since it is a proper noun (the name Jackie), we need to start it with a capital letter. Therefore, the corrected sentence becomes "My sister's name is Jackie."
