So if i were to quote an author and I want to add a later part to an earlier part by putting it in the middle of the first quote? an example :
The researcher, led by Woo-Suk Hwang, insist they cloned an Afghan hound, . . . [and] [o]ne of the dog's co-creators, Gerald Schatten of the University of Pittsburgh School of Medicine, described Snuppy . . . as 'a frisky, healthy, normal, rambunctious puppy.'
Would that be how to properly do it?
