Is this sentence correct:
1-They have two different types of DNA in different parts of their body.
The meaning is supposed to be, if I am not mistaken, that all in all they have two different types of DNA, but one type in each part of their body. In other words, the two types do not exist in the same part. I am not sure that is what the sentence is saying though. I can't make up my mind as to what it means (one type per part, two types per part, how many types in all if they have two types per part...)
To me (that is, what MY logic tells me), it means they have one type of DNA in one part of the body, and another type in the other part of the body.
However, having some context would help (me, at least). And also, I cannot imagine any creature having two different types of DNA . Are we talking about viruses, sci-fi creatures...(please excuse my ignorance on that ).
