Huntington’s disease usually occurs in middle age and results in the loss of muscle coordination and cognitive abilities. this disease is more prevalent in people originally from western europe. what is the most likely cause of this disease? a) a mutated gene b) loss of immunity c) high blood pressure d) high levels of glucose in the blood

Ans.

HD (Huntington's disease) is a genetic neurological disorder that occurs due to damage and death of brain  cells. it is caused by an autosomal dominant mutation in HTT (huntingtin) gene, having a trinucleotide repeat section that makes HTT protein.

The mutation leads to an increase in this nucleotide repeat count, associated with formation of altered or mutated huntingtin protein. These altered proteins show deleterious affect on brain cells and result in Huntington's disease.

Thus, the correct answer is 'option A). a mutated gene.'

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells
