Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When a protein needs to be made, which organelle is responsible for this task?
A
Nucleus
B
Ribosomes
C
Golgi Body
D
Mitochondria
Explanation: 

Detailed explanation-1: -The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

Detailed explanation-2: -The ribosome is universally responsible for synthesizing proteins by translating the genetic code transcribed in mRNA into an amino acid sequence.

Detailed explanation-3: -The nucleolus, an organelle is associated with Ribosome function.

Detailed explanation-4: -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.

Detailed explanation-5: -Ribosomes. Ribosomes are the protein factories of the cell. Composed of two subunits, they can be found floating freely in the cell’s cytoplasm or embedded within the endoplasmic reticulum.
