Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What are the “protein-makers” of a cell?
A
Ribosomes
B
Mitochondria
C
ER
D
Golgi Body
Explanation: 

Detailed explanation-1: -Ribosomes are cell organelles that function in the synthesis of proteins. They are present on the surface of rough endoplasmic reticulum. They produce proteins from amino acids by a process called protein synthesis. Therefore, ribosomes are called protein factories as they synthesize 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. Ribosomes use cellular accessory proteins, soluble transfer RNAs, and metabolic energy to accomplish the initiation, elongation, and termination of peptide synthesis.

Detailed explanation-3: -What looks like a jumble of rubber bands and twisty ties is the ribosome, the cellular protein factory. The ribosome is made up of proteins and strands of RNA, a chemical relative of DNA. It has two interlocked parts that behave as a single molecular machine to assemble all of the cell’s protein molecules.

Detailed explanation-4: -Endoplasmic reticulum with attached ribosomes is called rough ER. It looks bumpy under a microscope. The attached ribosomes make proteins that will be used inside the cell and proteins made for export out of the cell.
