Which of the following molecules is the most stable?
A) mRNA
B) hemoglobin
C) carbohydrates
D) rRNA
E) mitochondrial DNA

Question

Quizplus · Accepted Answer

Mitochondrial DNA is the most stable among the options given. It is highly compact and protected within the mitochondria, making it less susceptible to damage compared to other molecules like mRNA, which is relatively unstable and degrades quickly, and rRNA, which, although stable, does not have the same level of protection as mitochondrial DNA. Hemoglobin is a protein that, while stable in its functional form, does not compare to the inherent chemical stability of DNA. Carbohydrates vary widely in stability depending on their structure, but generally do not match the stability of mitochondrial DNA.
