During RNA splicing
A) introns are removed from RNA, and the remaining exons are connected to form a mature mRNA.
B) an RNA molecule is cut up into many small pieces and each piece forms a single mRNA.
C) exons are removed from RNA and the remaining introns are fused to form a single mRNA.
D) RNA is used to remove mutations from essential genes.

Question

During RNA splicing, introns are removed from RNA, and the remaining exons are connected to form a mature mRNA. This process is important for the formation of functional proteins, as it allows for the removal of non-coding sequences and the joining of coding sequences in the correct order. Option B is incorrect because RNA is not cut up into many small pieces during splicing. Option C is incorrect because it suggests that the exons are removed, whereas they are actually retained. Option D is incorrect because RNA splicing does not remove mutations from genes.
