Detailed explanation-1: -However, eukaryotic cells that specialize in producing proteins have particularly large numbers of ribosomes.

Detailed explanation-2: -Answer and Explanation: Large numbers of ribosomes are present in cells that specialize in producing proteins. Ribosomes are small cellular organelles that are found in all cells. They carry out the process of protein synthesis in the cells.

Detailed explanation-3: -Although ribosomes are costly, they are essential for translating the genetic code, carried in messenger RNA (mRNA) molecules, into all the proteins the cell needs.

Detailed explanation-4: -Ribosomes are remarkably abundant in cells. A single actively replicating eukaryotic cell, for example, may contain as many as 10 million ribosomes. In the bacterium Escherichia coli (a prokaryote), ribosomes may number as many as 15, 000, constituting as much as one-quarter of the cell’s total mass.

Detailed explanation-5: -A ribosome is the cellular machinery responsible for making proteins. There are many ribosomes in each cell, each made up of two subunits. These two subunits lock around the messenger RNA and then travel along the length of the messenger RNA molecule reading each three-letter codon.
