Which of the following would likely vary the least at any given time in a bacterium?
A. its genome
B. its transcriptome
C. its proteome
The correct answer is option A -the genome.
Explanation: Genome is the most conserved part in any organism and nature wants to reduce any change in DNA, although mutation occurs. For this, DNA has its repairing system and proof reading system where as RNA and proteins lacks that. m RNA and proteins degraded after their function where as genome remains upto the death and genome is the part which is transferred to the next generation, but protein and RNA does not.
So for all of these reasons, Genome will vary least among all of these.
