Why do individuals with spinocerebellar ataxia experience loss of muscle control, even though the ataxin-1 protein builds up only in the brain and
spinal cord?
A.
Inclusions can build up in all body systems and can cause
debilitating effects.
B.
Genetic mutations in the ataxin-1 protein cause muscular proteins
to change shape.
O
When the ubiquitin tagging system does not work effectively,
cellular waste can build up in the muscles.
OD.
The neurons affected by the ataxin-1 protein buildup are in a
region of the brain that manages muscle control.
