G1 RNA structure

RNA is a polymer chain of ribonucleotides joined by 3 5 phosphodiester bonds. The covalent structure is very similar to that for DNA except that uracil replaces thymine and ribose replaces deoxyribose. 

RNA molecules are largely single-stranded but there are regions of selfcomplementarity where the RNA chain forms internal double-stranded regions.

Like DNA (see Topic FI), RNA is a long polymer consisting of nucleotides joined by 3 5 phosphodiester bonds. However, there are some differences  

The corresponding ribonucleosides are adenosine, guanosine, cytidine and uridine. The corresponding ribonucleotides are adenosine 5 -triphosphate (ATP), guanosine 5 -triphosphate (GTP), cytidine 5 -triphosphate (CTP) and uridine 5 -triphosphate (UTP).
