Why is RNA better for the transmission of genetic information?
Options
- ARNA is more stable than DNA
- BRNA directly codes for the synthesis of proteins
- CRNA has a shorter life span than DNA
- DDNA depends on RNA for synthesis of proteins
Correct answer
B. RNA directly codes for the synthesis of proteins
Step-by-step solution
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 synthesizing machinery has evolved around RNA. The above discussion indicates that both RNA and DNA can function as genetic material, but DNA being more stable is preferred for storage of genetic information. For the transmission of genetic information, RNA
