Mutations and Protein Synthesis

Which organelle contains rRNA and reads the mRNA to synthesize a protein?

• Ribosome

• Nucleus

• Cytoplasm

• Nucleotide

What brings the amino acids to the ribosome to assemble a protein?

• mRNA
• tRNA
• rRNA
• DNA

When these bond together, they form a protein

• Amino Acids

• Peptide Bonds

• Ribose

• Nucleotides

How can a mutation in the DNA sequence result in NO change to the protein that is made?

• There are multiple codons that can code for the same amino acid and result in the same protein

• There is always a change in the protein when a mutation occurs

• Only the mRNA is used in protein synthesis so a mutation in the DNA would have no effect on the protein

• the order (sequence) of the nitrogen bases
• the color of the nitrogen bases
• the frequency (number) of nitrogen bases

Which best describes the role of mRNA in protein synthesis? 

• mRNA brings amino acids to the ribosome where they are connected to construct a protein.
• mRNA forms the peptide bonds connecting amino acids together to construct a protein 
• mRNA decodes the sequence of tRNA into the amino acids used to construct a protein
• mRNA brings the code of DNA to the ribosome where it is used to construct a protein
