Question

Tay–sachs disease is an autosomal recessive disorder. Homozygous recessive individuals lack a key enzyme called hexosaminidase a. True or False

Answer 1

Answer: True

Step-by-step explanation:

Tay-Sachs disease can be defined as an autosomal recessive disorder in which there is a mutation on the hexa gene on the chromosome number 15 which codes for the subunit of the enzyme hexosaminidase.

This gene is inherited from a parent in an autosomal recessive manner. It is a genetic order which leads to destruction of nerve cells in the brain.

There is a hearing loss, seizures, and inability to move. These are some of the symptoms of Tay-sachs disease.
