Choose the nucleotide sequence of the RNA strand that would be complementary to the following strand: 
GTAGTCA

• UATUAGA

• ACGACTG

• CAUCAGU

• CATCAGT

The main function of tRNA is to...

• carry a message that, when translated, forms proteins

• form a portion of ribosomes

• string together complementary RNA and DNA strands

• bring amino acids from the cytoplasm to the ribosomes

What is the term for a three-nucleotide mRNA sequence that codes for an amino acid?

• base

• codon

• amine

• serine

Which phrase best describes translation?

• converts mRNA into a polypeptide or protein

• catalyzes bonds between amino acids

• produces RNA from DNA molecules

• recycles tRNA molecules for reuse

Which of the following is the site of transcription?

• vacuole

• lysosome

• nucleus

• ribosome

Which of the following is the site of translation?

• vacuole

• lysosome

• nucleus

• ribosome

Which of the following is created in the nucleus and carries the genetic code to the cytoplasm?

• DNA

What would happen if we did not have start codons?

• Polypeptide chains would continue to grow

• Amino acids would bind to tRNA

• Protein synthesis wouldn't occur

• mRNA would form a double strand
