Given below are two statements: Statement I: RNA mutates at a faster rate. Statement II: Viruses having RNA genome and shorter life span mutate and evolve faster. In the light of the above statements, choose the correct answer from the options given below:

Given below are two statements: Statement I: RNA being unstable, mutate at a faster rate. Statement II: RNA can directly code for synthesis of proteins, hence can easily express the characters. In the light of the above statements, choose the correct answer from the options given below:

Given below are two statements : Statement I: The process of copying genetic information from one strand of the DNA into RNA is termed as transcription. Statement II : A transcription unit in DNA is defined primarily by the three regions in the DNA, i.e., a promotor, the structural gene and a terminator. In the light of the above statements, choose the correct answer from the options given below :
