Biology 4/23/21 Lesson Recap

Translation takes place in the 

• ribosome
• chloroplast
• nucleus
• mitochondria

Brings the amino acids to the ribosome

• mRNA
• tRNA
• rRNA
• DNA

What would be the tRNA anticodon for the mRNA codon CAG?

• GTC
• GUC
• CUG
• CAG

What is the term for a three-nucleotide sequence that codes for an amino acid?

• base
• codon
• amine
• serine

Which phrase best describes translation?

• converts mRNA into a polypeptide
• catalyzes bonds between amino acids
• produces RNA from DNA molecules
• recycles tRNA molecules for reuse

What type of bonds are forming during translation?

• Peptide bonds
• Hydrogen bonds
• Acid bonds

How many amino acids are coded for by this sequence of nucleotides:
ATG GGA ACT CCA

• 4
• 2
• 6
• 12

The job of tRNA is to

• carry amino acids to the ribisomes
• carry ribisomes to the ER
• carry glucose to mitochondria
• carry mRNA out of the nucleus

What would happen if we did not have start codons?

• Polypeptide chains would continue to grow
• Amino acids would bind to tRNA
• Protein synthesis wouldn't occur
• mRNA would form a double strand

What is the correct amino acid sequence for the mRNA code AUGCCAGUAUGA

• Met-Pro-Ala-Val
• Met-Pro-Val
• Tyr-Gly-His
• Tyr-Gly-Arg-His
