Read the paragraph and answer the questions given below: With the help of RNA, the genes present in the form of DNA particioate in the functioning of cell and thereby control the structure and functioning of the body. Information about protein synthesis is stored in the DNA and synthesis of appropriate proteins as per synthesized by DNA through rthe RNA. This is called 'Central Dogma'. mRNA is produced as per the sequence of nucleotides on DNA. Only one of the two strands of DNA is used in this process. The seqience of nucleotides in mRNA being produced is always complementary to the DNA strand used for synthesis. Besides, there is uracil in RNA instead of thymine of DNA. This is process of RNA synthesis is called 'transcription'. What is the similarity between mRNA and DNA?
