Hello students, our next topic for the MCQ is ‘STRUCTURE OF RNA’. The DNA in our body have all the required information or blueprint for the cell to grow, function and replicate. The RNA carries out this instructions and it copies and transfers genetic code from the DNA. So we can say that DNA makes RNA and RNA makes proteins.
The following MCQ will provide you more information about structure of RNA.
