Question

many different types of mutations can occur within the body. tay-sachs disease is a deadly disorder that is caused by a missing codon in the gene coding for production of the hex a enzyme in the body. which type of mutation is responsible for causing tay-sachs disease?
○ substitution
○ replacement
○ insertion
○ deletion

Explanation:

Tay - Sachs disease is caused by a missing codon in the gene for hex A enzyme. A deletion mutation involves the removal of a segment of DNA (including codons), while substitution replaces one base, insertion adds a segment, and replacement is not a standard mutation type. So the mutation type here is deletion.

Answer:

D. deletion
