The organelle that makes protein using coded instructions from the nucleus is the ribosome.

Here's how it works:

1. DNA in the nucleus contains the genetic code for making proteins.

2. Transcription: This code is copied into a molecule called messenger RNA (mRNA).

3. mRNA travels out of the nucleus and into the cytoplasm.

4. Ribosomes attach to the mRNA and read the code.

5. Translation: Ribosomes use the code to assemble amino acids into a specific protein chain.

So, ribosomes are like tiny protein factories within the cell, following instructions from the nucleus to create the proteins needed for various cellular functions.
