Concept 2- Protein Synthesis

Which is the best statement to explain the relationship between genes and proteins.

• Genes contain information.

• Genes contain directions for making proteins.

• Proteins are made of amino acids.

• Proteins contain directions for making genes.

Identify the central dogma

• DNA translates into mRna, then mRNA transcribes into proteins
• DNA transcribes mRNA, then the mRNA translates into proteins.

What is the role of mRNA?

• Carries amino acids to the ribosome and mRNA
• composes the ribosome
• copies instructions from DNA

What is the role of tRNA?

• Carries amino acids to the ribosome and mRNA
• composes the ribosome
• copies instructions from DNA

What is the role of rRNA?

• copies instructions from DNA
• composes the ribosome
• Carries amino acids to the ribosome and mRNA

What is the difference between a codon and anticodon?

• The codon is found on the mRNA and the anticodon is located on the tRNA.

• The anticodon is found on the mRNA and the codon is located on the tRNA.

• They both contain 3 nucleotides.

• They are both coded in RNA.

Transcribe the DNA- TAC ACC CGG TTT ATT

What would be the order of the amino acids in the protein?

AUG UGG GCC AAA UAA

• met, trp, ala, lys, ter

• ser, thr, arg, phe, ile

• Met, phe, ala, arg, cys

• asp, tyr, ter, val, gln

What could be a result of a mistake in the translation process?

• It could code for the wrong amino acid

• It could change the DNA bases.

• The mRNA coded for the incorrect DNA.

• The DNA copied the incorrect DNA

What step of Protein Synthesis is identified by this star?

• Replication

• Transcription

• Duplication

• Translation
