Question
Which statement about the genomes of organisms is false? -Most of the DNA in a bacterium codes for either RNA or protein. -Noncoding regions of the DNA have higher mutation rates than coding regions. -There is some correlation between genome size and complexity of the organism. -Pseudogenes evolved from functional genes. -The total size of the genome of eukaryotes varies little from organism to organism.

a). Most of the DNA in a bacterium codes for either RNA or protein ----> TRUE (becasue it contains less "junk" DNA, which is more in humans and other higher level organisms)
b). Noncoding regions of the DNA have higher mutation rates than coding regions ---> TRUE
c). There is some correlation between genome size and complexity of the organism ---> TRUE (complex organisms contain more genome)
d). Pseudogenes evolved from functional genes ---> TRUE
e). The total size of the genome of eukaryotes varies little from organism to organism ----> FALSE (it greately varies and is more complex in higher animals)
