Question

which carries the code for protein synthesis from the cell nucleus to the cytoplasm?
○ dna
○ trna
○ rrna
○ mrna

Explanation:

DNA holds the genetic code but stays in the nucleus. tRNA transfers amino acids during protein synthesis, and rRNA forms part of ribosomes. mRNA is transcribed from DNA in the nucleus and travels to the cytoplasm to carry the protein synthesis code.

Answer:

mRNA
