mRNA carries the information for making proteins to the ribosomes.

Here's why:

* mRNA (messenger RNA): This type of RNA carries the genetic code from DNA in the nucleus to the ribosomes in the cytoplasm.

* Ribosomes: These are the protein synthesis factories of the cell. They read the mRNA code and use it as instructions to assemble amino acids into a specific protein.

So, the journey of protein synthesis goes:

1. DNA in the nucleus: Holds the genetic code.

2. Transcription: DNA is copied into mRNA.

3. mRNA travels to the ribosomes: In the cytoplasm.

4. Translation: Ribosomes read the mRNA code and build the protein.
