     Sentence="What word fits in the gap?\n\nWhen a gene is expressed ... is produced."
     CorrectMessage="That's right. The first step in gene expression is the synthesis of mRNA. Therefore the level of a specific mRNA molecules reflects the gene expression level of the (corresponding) gene."
     WrongMessage="No. This is incorrect - please try again!"

     Sentence="All genes are expressed in all the cells.\n\nIs this statement true?"
     CorrectMessage="Excellent! All cells/tissues have the same genes, but for instance only fat tissue relevant genes are expressed in fat tissue."

        <Option Sentence="No, only genes that are relevant for that particular cell are expressed." IsCorrectAnswer="true" />
        <Option Sentence="That's true." />
        <Option Sentence="No, all genes are only expressed in the young cells and then the expression level decreases." />
        <Option Sentence="No, only half of them are expressed in all the cells." />

     Sentence="If mRNA from gene A is very abundant in fat tissue from obese and rare in fat tissue from lean it shows us that .... ?"
     CorrectMessage="That's right.\n\nA high mRNA level reflects a high expression level. When the expression level differs between obese and lean, the gene might influence the obesity status.\n\nLet's get some samples for our experiment!"
     WrongMessage="No. This is incorrect - please try again!"
