The ribosomes are the cellular organelles responsible for producing proteins in an animal cell.

Here's a breakdown:

* Ribosomes are tiny, complex structures made of RNA and protein. They are the sites of protein synthesis.

* Messenger RNA (mRNA) carries the genetic code from DNA in the nucleus to the ribosomes.

* Transfer RNA (tRNA) brings amino acids to the ribosomes, where they are linked together according to the instructions in the mRNA, forming a protein.

So, in essence, the ribosomes act like tiny factories, using the instructions from the DNA to build proteins from individual amino acids.
