Question

Based on the table of average intron frequency given below,predict the relative order of genome size for these four eukaryotic organisms. 
A) Homo sapiens > Arabidopsis thaliana > Plasmodium falciparum > Cryptosporidium parvum 
B) Cryptosporidium parvum > Plasmodium falciparum > Arabidopsis thaliana > Homo sapiens 
C) Homo sapiens > Cryptosporidium parvum > Plasmodium falciparum > Arabidopsis thaliana 
D) Intron frequency cannot be used to predict genome size in eukaryotes.

Quizplus · Accepted Answer

The table shows that the average intron frequency is highest in Homo sapiens and lowest in Cryptosporidium parvum. As introns are non-coding regions of DNA, the presence of more introns suggests a larger genome size. Therefore, the order of genome size can be predicted as Homo sapiens > Arabidopsis thaliana > Plasmodium falciparum > Cryptosporidium parvum. Choice A is the only option that correctly reflects this order.
