Protein Synthesis

A codon is necessary in the process of translation because it codes for a

• Specific nitrogen base

• Specific amino acid

• Specific anticodon

• Specific tRNA molecule

What would terminate translation?

• The arrival of a transfer RNA molecule to the A site of the ribosome

• The transcription and processing of a new RNA molecule

• The arrival of the ribosome to a stop codon, such as UGA

• The attachment of a complementary codon to another codon

A DNA sequence is shown below. TAGGAGCAT What is produced when the sequence is transcribed?

• A chain of three amino acids

• A set of three tRNA molecules

• A section of DNA with the base sequence of ATCCTCGTA

• A section of mRNA with the base sequence of AUCCUCGUA

A small portion of an mRNA sequence is shown below. AAUGACUGGCUC Starting with the first base, how many codons does this portion of the sequence contain?

• 1

• 4

• 6

• 12

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.

What is the product of transcription?

• DNA

• mRNA

• tRNA

• proteins

During transcription, this type of ribonucleic acid is responsible for copying the DNA and brining it out of the nucleus.

• tRNA

• mRNA

• rRNA

• dRNA

Where does TRANSCRIPTION occur?

• Nucleus

• Ribosome

• Cytoplasm

• Mitochondria

When these bond together, they form a protein

• Amino Acids

• Peptide Bonds

• Ribose

• Nucleotides
