Answer:

a. DNA to RNA to proteins.

Explanation:

DNA is the genetic material which is transcribed into RNA in nucleus. The mRNA leaves nucleus and joins ribosomes for the process of protein synthesis. The nucleotide sequence of mRNA serves as template for protein synthesis. Hence gene expression occurs in following direction:

DNA------> RNA--------> Protein

This unidirectional flow of genetic information is also called as central dogma.

kirill115 [55]

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.'
