If a substance is very sour and has a ph of 4, then you would expect the litmus paper to turn into the shade of red. A substance that is sour and has a pH level that is below 7 would indicate that the substance is an acid or has acidic properties. For an acidic solution, the litmus would be red in color. If a blue litmus paper is used, then it would turn into red while if a red litmus paper is used, then it would remain as red. There is also a general type of litmus paper where the color change range from violet to red. A litmus is widely used in distinguishing acid and bases. It can be used in liquid solutions and in gas mixtures. <span />

Answer:
C) translation rate
Explanation:
The process of gene expression involves DNA transcription into mRNA and translation of mRNA into protein.
During transcription, genetic message in DNA is encoded into mRNA. The encoded messages are then translated into their respective amino acids during the process of translation.
<em>Hence, if a virus uses its genome as mRNA, the next stage will be to translate the messages in the mRNA into amino acids. Translation rate is expected to be measurable.</em>
The correct option is C.
