Question : 3
From what you have learnt, can you tell whether enzymes are bigger or DNA is bigger in molecular size? How did you know?
Share
Enzymes are smaller in size than DNA molecules. We know this because DNA contains genetic information for the development and functioning of all living organisms. It contains instructions for the synthesis of proteins and DNA molecules. On the other hand, enzymes are proteins which are synthesised from a small stretch of DNA known as ‘genes’, which are involved in the production of the polypeptide chain.
