Which organelle makes proteins using coded instructions that come from the nucleus?
A
Golgi apparatus
B
vacuole
C
mitochondrion
D
ribosome
Explanation: 

Detailed explanation-1: -Ribosomes Proteins are assembled on ribosomes. Ribosomes are small particles of RNA and protein found throughout the cytoplasm in eukaryotes and prokaryotes. Ribosomes produce proteins by following instructions that come from DNA.

Detailed explanation-2: -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-3: -The mRNA attaches to a structure called a ribosome that can read the genetic information. As the mRNA passes through the ribosome, another type of RNA called transfer RNA (tRNA) carries a protein building block called an amino acid to the ribosome.

Detailed explanation-4: -For creating proteins there is a special organelle in the cell called the ribosome. The ribosome is found in the cytoplasm of the cell. However, the genetic code on the DNA is contained in the nucleus, which is in a different part of the cell.

Detailed explanation-5: -It carries the instructions from the DNA in the nucleus to the ribosomes where proteins are made in the cytoplasm of the cell. RNA picks up specific amino acids from the cytoplasm of the cell and delivers them to the ribosomes where protein synthesis takes place. More items •21-Feb-2022
