Question

in eukaryotic cells, dna is stored in the nucleus. but amino acids are assembled into proteins at ribosomes found throughout the cells cytoplasm or attached to the endoplasmic reticulum. certain types of ribonucleic acid, or rna, act as messengers by copying the instructions in a gene and carrying them from the nucleus to the ribosomes. then, the ribosomes use the genetic code to build a protein. complete the paragraph. the job of is to copy the genetic instructions contained within in the and carry these instructions to a , where they can be used to make proteins.

Explanation:

The text describes the process of protein - synthesis in eukaryotic cells. RNA copies the genetic instructions from DNA in the nucleus and takes them to ribosomes for protein - building.

Answer:

The job of RNA is to copy the genetic instructions contained within DNA in the nucleus and carry these instructions to a ribosome, where they can be used to make proteins.
