What does mRNA do in protein synthesis? What does tRNA do? mRNA: Aggressive, always gets what it wants. tRNA: More of a caring personality. mRNA: Stores genetic code; hangs out in the nucleus until DNA copies it and brings it to the ribosome. tRNA: Facilitates the movement of DNA to the ribosome along molecular transport channels. mRNA: Copies tRNA and brings amino acids to the ribosome. tRNA: Brings the DNA code from the nucleus to the ribosome. mRNA: Copies DNA and brings the code to the ribosome; tRNA: Brings amino acids to the ribosome so that they can be matched to the mRNA code. mRNA: Copies DNA and brings the code to the mitochondria. tRNA: Brings amino acids to the ribosome so that they can be matched to the mRNA code.

Where does tRNA come from and how does rRNA fit in? mRNA comes from transcription, right, and then mRNA and tRNA join together to make lines of amino acids to make proteins. What does rRNA do?

What is the function of a tRNA molecule? To bring an amino acid to a ribosome To carry the instructions for making a protein to a ribosome To attach to mRNA and take it to a ribosome To covalently bond amino acids at a ribosome
For each of the following, identify the type of RNA involved (mRNA, rRNA, or tRNA). _____ a. Transports the correct amino acid to the ribosome, using the information encoded in the mRNA. _____ b. Is a major component of ribosomes. _____ c. Specifies the order of amino acids in a protein, using a series of three-base codons, where different amino acids are specified by particular codons. _____ d. Contains a three-base anticodon that pairs with a complementary codon revealed in the mRNA. _____ e. Assists in making the bonds that link amino acids together to make a protein.
