What if RNA suddenly became double stranded? Would this be good or bad? What processes would it impact and would it improve, modify, or hinder those processes? What could it mean for the long-term survival of a species? (this question is in relation to molecular biology and inheritance patterns) I know it would affect protein synthesis, but I'm not sure what difference it makes if it is single stranded or double stranded?
Homework Answers
If RNA becomes double stranded, then ribosome can not bind to it. Because the specific sequence present in ribosomes can not interact with ds mRNA and there is no binding of mRNA. Hence the peptidyl transferase activity of ribosome is not useful in double stranded mRNA.
It would be bad because protein synthesis ( translation) will not occur and there is no expression of genes.
The double stranded RNA can not interact with miRNA and si RNA. This miRNA and si RNA leads to cleaving of RNA. Hence RNA half life time enhances and there is long term survival of species.
