Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Where are proteins made? These are small, grain-like or rod shaped organelles.
A
Golgi body
B
Mitoichondrion
C
Chromosomes
D
Ribosomes
Explanation: 

Detailed explanation-1: -ribosome – A small grain-like structure in the cytoplasm of a cell where proteins are made.

Detailed explanation-2: -Ribosomes are the sites in a cell in which protein synthesis takes place. Cells have many ribosomes, and the exact number depends on how active a particular cell is in synthesizing proteins.

Detailed explanation-3: -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-4: -The ribosome is universally responsible for synthesizing proteins by translating the genetic code transcribed in mRNA into an amino acid sequence.

Detailed explanation-5: -Synthesis of new proteins starts in the nucleus, where ribosomes get their instruction to begin the process. Sections of DNA (genes), encoding a specific protein, are copied over to messenger RNA (mRNA) strands in a process called transcription.
