In reference to a segment of DNA, which of the following molecules contains the fewest number of nucleotides? Correct Answer a single strand of complementary DNA (cDNA) made from the original DNA

D. The cDNA lacks the introns found in the original DNA segment and contains only the exons necessary for making mRNA. The number of nucleotides in the introns of a primary RNA transcript varies dramatically, from hundreds to hundreds of thousands of nucleotides. The intron nucleotides are removed by snRNPs during RNA splicing (processing of RNA while still in the nucleus), thus reducing the length of the final RNA considerably. A DNA segment with a point mutation (a single nucleotide replaced, added, or deleted) will differ from the original DNA segment by, at most, only one nucleotide. The primary RNA transcript, containing both introns and exons, will contain the same number of nucleotides as the original DNA segment.
