What causes proteins to have different function when a mutation happens?

• Changes in amino acid sequence lead to changes in protein structure and function.
• Proteins with mutations lose all function
• Mutations always lead to improved protein function
• Mutations have no impact on protein function

How do carcinogens cause cancer to happen? Ex. Chemicals, Radiation

• Carcinogens cause cancer by improving DNA repair mechanisms.
• Carcinogens cause cancer by causing mutations in the DNA.

How do DNA, mRNA, tRNA, and amino acids work together to make a protein?

• DNA is translated into tRNA, which then assembles amino acids into a protein
• mRNA is transcribed into DNA, tRNA brings amino acids to the ribosome based on DNA codons
• Amino acids are directly assembled into a protein without the need for DNA, mRNA, or tRNA
• DNA is transcribed into mRNA, tRNA brings amino acids to the ribosome based on mRNA codons, and the ribosome assembles the amino acids into a protein.
