Assume that a mutation occurs in the gene responsible for the production of hexosaminidase a

A Tay-Sachs disease is a rare degenerative disease that affects the brain and central nervous system and is hereditary, autosomal recessive (more common in descendants of Hebrews).

It is one of the diseases by lysosomal deposition. Individuals who suffer are unable to produce a lysosomal enzyme called hexosaminidase-A that participates in the degradation of the ganglia, a type of sphingolipid, which accumulate and degenerate in the central nervous system. It is included within lipidosis or lipid storage diseases.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
