DNA to Protein Synthesis & Mutations Review

In terms of DNA structure, what sets living organisms apart from one another?

• deoxyribose sugar

• hydrogen bonds

• sugar-phosphate backbone

• order of nucleotides

DNA and RNA are necessary for protein synthesis; which answer best supports their differences?

• DNA and RNA contain a sugar phosphate backbone

• DNA and RNA contain nitrogen bases A, G, and C.

• DNA has Thymine and RNA has Uracil

• DNA and RNA build proteins

What must first be done in order to build a protein?

• Messenger RNA attaches to a ribosome

• DNA serves as a template for RNA production

• Amino Acids are bonded together

• RNA moves from the nucleus to the cytoplasm

Which image best represents a strand of RNA?

• 
• 
• 

Which image best represents transcription?

• 
• 
• 
• 

What do DNA Replication and Transcription have in common?

• Thymine

• Uracil

• Hydrogen bonds between nitrogen bases must be broken

• duplicate carbon bonds in the sugar-phosphate ladder

When does the ribosome begin the process of translation?

• When the hydrogen bonds between the base pairs have been broken

• When the codon UGA has been reached

• When a mutation occurs

• When the first AUG codon has been read

What does letter E represent in the image?

• an amino acid

• a codon

• a tRNA

• an anticodon

UAA, UGA, and UAG represent the termination of translation because

• all 3 are a stop codon

• all 3 are mutations

• all 3 are DNA nucleotides

Which RNA molecule transports amino acids to the ribosome?

• mRNA

• rRNA

• tRNA
