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.'
Micro evolution by mutation in the DNA
Answer:
Going paperless could possibly lead to data risks when computer systems crashes.
Explanation:
This is the only choice that describes a negative outcome of going green. Data risks and computer systems crashing aren't really benefits
