Protein Synthesis AP Bio

What is the end product of translation?

• mRNA that can leave the nucleus

• Amino acid chain

• monosaccharide chain

• Anticodon

A certain gene codes for a polypeptide that is 120 amino acids long. Approximately how many nucleotides long is the mRNA that codes for this polypeptide likely to be?

• 360

• 480

• 40

• 30

Translate the following RNA sequence:
AUG AAU UGU UGA

• Met-Phe-Cys-Stop

• Met-Asn-Cys-Stop

• Met-Asn-Cys-Trp

• Tyr-Leu-Thr-Thr

Which occur during protein synthesis?

• 
  replication, translation

• 
  transcription, translation

• 
  replication, transcription, translation

• 
  translation, transcription, replication

Which type of RNA is responsible for bringing amino acids to the ribosome?

• mRNA

• rRNA

• tRNA

• DNA

If there is an error in transcription, what could happen as a result?

• The nucleotides that make up the protein will change.

• The protein that is made will not be affected.

• New amino acids will be created to make a new protein.

• The protein that is made may have a different structure or function.

During translation, what does the tRNA deliver to the ribosomes? (a)  

• 
  amino acids

• 
  DNA

• mRNA

• 
  proteins

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

This type of RNA transports amino acids to the ribosome for protein synthesis.

• mRNA

• rRNA

• tRNA

• All of the above

What is the product of transcription?

• DNA

• mRNA

• tRNA

• proteins
