If a splice site sequence was mutated so that splicing did not take place, what would the effect be on the mrna

Splicing is the cutting of some parts of the RNA resultant of the transcription (pre-mRNA) turning it into a mature messenger RNA (mRNA). The parts that are cut off are called introns and will not have a part on the translation. When splicing does not take place in a certain site, intron will not be removed there and that will affect how mRNA will be then translated.

Step 1. Solve the equation for x
Step 2. Find the intersection
Step 3. Find the union -> x = - 8/3
Step 4. The equation has 2 solutions
x1 = -8/3
x2= 16/3
