A very rare disease will cause damage to the ribosomes in cells. what would be the direct effect of this disease?
DochEvi [55]

Answer:

A rare disease that causes damage to the cell's ribosomes will have as a direct effect the inability to perform protein synthesis.

Explanation:

Ribosomes are cellular organelles formed by proteins and a type of RNA called ribosomal RNA, whose function is to translate the genetic code of the mRNA codon sequence and convert it into amino acids. This implies the first step for protein synthesis to occur.

<em><u>If a rare disease could structurally or functionally affect the ribosomes, the translation of mRNA into amino acids could not occur, so protein synthesis in the cell would not be possible</u></em>.

The consequences of the lack of protein synthesis involve severe consequences on the structure and function of a living organism.
