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.
Which statement about the genomes of organisms is false?

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.
Frequently Asked Questions
What scientific concept do you need to know in order to solve this problem?
Our tutors have indicated that to solve this problem you will need to apply the DNA as the Genetic Material concept. You can view video lessons to learn DNA as the Genetic Material. Or if you need more DNA as the Genetic Material practice, you can also practice DNA as the Genetic Material practice problems.
What professor is this problem relevant for?
Based on our data, we think this problem is relevant for Professor Hittinger & Tilmann's class at UW-MADISON.
