Question

there iS a coding on RNA strand AAUUGGCC calculate how many h-bond is formed in RNA
strand????

Answer 1

So, if you want to you can start by finding your complementary strand... but it really doesn't matter because A-U G-C is what it always is.
A-U has 2 hydrogen bonds
G-C has 3.
So, with your strand AAUUGGCC you can replace A&U with 2 and G&C with 3 and sum

2+2+2+2+3+3+3+3 = 20
or
2*4+3*4 = 20

There are 20 hydrogen bonds in this strand (assuming they stay as watson-crick base pairs).

Answer 2

0 h-bond as RNA is single stranded

Answer 3

I assumed you were talking about double stranded RNA, such as mRNA.

Answer 4

but mRNA is also single stranded
