Concept

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

FREE Expert Solution

a) Most of the DNA in a bacterium codes for either RNA or protein. → TRUE

Prokaryotes contain less "junk DNA" or noncoding DNA.


b) Noncoding regions of the DNA have higher mutation rates than coding regions. → TRUE

Coding regions of DNA are more highly preserved than noncoding regions.
