Answer:
False
Explanation:
Introns need to be removed precisely because the reading frame will be shifted if removed even single nucleotide too many or leaving an intronic nucleotide in the spliced mRNA .
Extra amino acids will be inserted if large pieces of introns are left in the mature messenger RNA.
In both cases, aberrant protien will be produced if the RNA splicing is not precise, hence they are needed to be removed by precision.

Answer:
The correct answer is - option C.
Explanation:
CFTR is a short form of cystic fibrosis transmembrane conductance regulator protein which is caused by a recessive mutation in this protein. This mutation results in the accumulation of mucus in secretory organs.
As the disease is a recessive disease, for the mutant phenotype to expressed both copies of the allele required to be recessive.
The mother is negative for the CFTR. Hence, she will not transfer the mutant allele to her child So, the child would have a wild-type phenotype even if the father having two copies of recessive allele.
Thus, the correct answer is - option C.
