Based on the role of ubiquitin in protein deconstruction as stated in the passage, the correct options are as follows:
- to tag waste proteins for recycling in the proteasomes; option A.
- Wastes will build up in vital organs, and the organism will experience disease; option D
- the neurons affected by the ataxin-1 protein buildup are in a region of the brain that manages muscle control; option D.
<h3>What are phrases?</h3>
Phrases refers to a group of words which contains a verb but which on their own do not make complete sense.
In the description of the role of Ubiquitin, it is described as a small polypeptide chain containing 76 amino acids. The main tole of ubiquitin is to tag proteins for deconstruction in the proteasomes.
Therefore, the phrase describes the purpose of ubiquitin is to tag waste proteins for recycling in the proteasomes; option A.
Based on the passage, the statement that describes the overall consequence of proteins containing mutations is: Wastes will build up in vital organs, and the organism will experience disease; option D
Individuals with spinocerebellar ataxia experience loss of muscle control, even though the ataxin-1 protein builds up only in the brain and spinal cord because the neurons affected by the ataxin-1 protein buildup are in a region of the brain that manages muscle control; option D.
In conclusion, mutations in ubiquitin-tagged proteins will result in accumulation in the body since they cannot be deconstructed in the proteasomes.
