Transcription goes from:

• DNA to DNA

• DNA to Protein

• DNA to RNA

• None of the above

Transcription takes place in the

• nucleus

Translation occurs:

• Outside of the Nucleus
• Inside of the Nucleus

Smaller segments of RNA nucleotides that transport amino acids to the ribosomes.

• mRNA
• tRNA
• rRNA
• DNA

Which defines a codon in mRNA?
