After nucleic acid hybridization with the DNA from a eukaryotic gene as the target and mRNA as the probe, you observe a 1:1 complementarity between the RNA and the DNA.From this result, you can infer that
A) there are splicing variants of this gene in the population.
B) the gene lacks introns.
C) the gene has one intron.
D) the gene has two or more introns.
E) the mRNA sequence has been scrambled.

If there is 1:1 complementarity between the RNA and the DNA after nucleic acid hybridization, it suggests that the mRNA probe hybridized with the entire target DNA sequence without any gaps. This indicates that there were no introns present in the gene since introns would have appeared as regions of non-complementarity between the RNA probe and the DNA target.
