DNA to Proteins

What is the role of RNA in protein synthesis?

• Acts as a messenger between DNA and cellular processes

• Replicates DNA during cell division

• Packages DNA with proteins

• Codes for specific traits or proteins

During transcription, which base does adenine pair with in RNA?

• Uracil

• Thymine

• Cytosine

• Guanine

What is the function of tRNA during translation?

• Matches codons on the mRNA with the appropriate amino acids

• Separates the DNA strands

• Adds complementary nucleotides to mRNA

• Binds to the stop codon

How many possible codons are there in the genetic code?

• 64

• 20

• 4

• 32

What happens when a stop codon reaches the ribosome's A site during translation?

• A release factor binds to the stop codon, releasing the polypeptide chain

• The ribosome starts a new polypeptide chain

• tRNA adds an amino acid to the chain

• RNA polymerase detaches from the DNA
