Detailed explanation-1: -Explanation: Ribosomes are found in the cytoplasm or attached to the endoplasmic reticulum. Ribosomes are important because they produce proteins and proteins are vital for all living organisms. Since ribosomes are connected to the production of proteins, this process would stop.

Detailed explanation-2: -So, the correct answer is ‘Protein will not be formed’.

Detailed explanation-3: -Attacking Ribosomes Ricin clips off a single adenine base at the tip of this loop, which is enough to inactivate the ribosome permanently. This is why ricin is so incredibly toxic: it can hop from ribosome to ribosome, destroying each one in turn, until there are no active ones left in the cell.

Detailed explanation-4: -The researchers found that the defective ribosomes tend to make a specific kind of mistake when translating the genetic code. This mistake changes specific patterns of gene expression in cells, consistent with changes that can lead to cancer. The mistakes make an already unstable set of molecules even more unstable.

Detailed explanation-5: -Without ribosome biogenesis, translation of mRNA into protein ceases and cellular growth stops.
