Which one of the following statements is correct about RNA ? |
RNA directly codes for proteins, making it easier to express characters. RNA stabilizes DNA to prevent mutations. RNA is a more stable form of genetic material for long-term storage. None of the above |
RNA directly codes for proteins, making it easier to express characters. |
The correct answer is Option (1) –RNA directly codes for proteins, making it easier to express characters. Both DNA and RNA are able to mutate. In fact, RNA being unstable, mutate at a faster rate. Consequently, viruses having RNA genome and having shorter life span mutate and evolve faster. RNA can directly code for the synthesis of proteins, hence can easily express the characters. DNA, however, is dependent on RNA for synthesis of proteins. The protein synthesising machinery has evolved around RNA. |
