There's this little paragraph in my textbook, parts of which I find redundant. My teacher is absolutely fine with this ("Aaron, you've got to write down what's in the textbook if you want to score in exams, nothing extra...."), but all the same.....
It's regarding 'Why does transcription occur at one DNA strand at a time?'
According to their first point, forming two complementary RNA strands would result in the production of two different proteins for the same character.
Now according to their second point, formation of two complementary strands of RNA side-by-side would just result in them pairing to form dsRNA, which would be transcriptionally inactive and therefore wouldn't take part in the translation process.
The thing is, they've mentioned the second point after the first point, which I find confusing. For if the second point were correct, the first point wouldn't even exist.
Is there a sound reason for the points being stated this way? Am I missing something here?
