Ans.
Fragile X syndrome is defined as a genetic disease, results in cognitive impairment and mental problems.
It is caused by a mutation in FMR1 gene that causes an increase in the CGG trinucleotide units in the gene. This is an example of insertion mutation as it involves addition of nucleotide sequences to the gene.
The FMR1 gene codes for a protein, which is necessary for normal cognitive functions and defect in this protein, due to mutated gene leads to development of disorder.
Thus, the correct answer is option D). 'insertion.'
Interleukin-5 can both promote the growth of B cells and eosinophils which are cleared when not exposed to IL-5.
<h3>What is Interleukin-5?</h3>
Interleukin-5 (IL-5) is a cytokine that induces the growth of different immune cells including B cells and eosinophils.
In consequence, in this case. it is expected to observe the outcome (immune response) of immune cells in the presence of IL-5.
In conclusion, Interleukin-5 can both promote the growth of B cells and eosinophils which are cleared when not exposed to IL-5.
