Question

Quizplus · Accepted Answer

Mitochondrial DNA is less subject to degradation and has a higher mutation rate compared to chromosomal DNA, making it useful as an evolutionary time clock. Chloroplast DNA is also less subject to degradation but is only found in plants and some protists, making it less widely applicable as an evolutionary time clock. rRNA, mRNA, and tRNA are all involved in gene expression and translation but do not have the same level of stability or mutation rate as mitochondrial DNA.
