Answer: D) Degradation of defective proteins activates mRNA repair pathways
Explanation:
A recent publication (J Phys Condens Matter. 2013. 18;25(37):374104.) provided the information on this matter. According to researcher RNA polymerase have ability to backtrack and translocate the error on both RNA transcript and DNA template. By doing so RNA polymerase cleave the defective part on RNA transcriptome by the process called proofreading. While proofreading contribute in accuracy of transcription but on contrary it also slower the process of transcription.
- absorbs and blocks some of the harmful UV rays
- keeps oxygen and other gassed inside the atmosphere
- helps maintain the planet’s temperature to support life
