Check Your pm.

[Deadly_king]

Check Your pm.

Don't mind girl........but from now on it would be best that you post your explanations here.

This may be useful to other students as well.

And also if ever( I doubt that ;( ) you make mistakes, others can correct you.

No,no no. I didn't know that he had posted his questions here. That person pm'ed me those questions. So, naturally I cleared his doubts via pm. Get it?

Ooh.............now it's clear.

Well, it was the same thing for me before. But then I opted to post both questions and answers so that others can benefit from them as well

Thanks for not misunderstanding me

But the king is not as sweet as his daughter.

I dont think the first evidence is required but the second one about DNA replication and semi-conservative method is definitely needed.
I say, you check your syllabus.
