Differentiating Point and Frameshift Mutations

What is the primary goal of Keras in cancer treatment?

• To create a universal cure for all diseases

• To develop new types of cancer

• To improve the lives of cancer patients by analyzing them at a molecular level

• To replace chemotherapy with herbal treatments

What is the blueprint for making RNA in our cells?

• Amino acids

• Lipids

• Proteins

• DNA

Which of the following is NOT a function of proteins in living organisms?

• Delivering oxygen to the muscles

• Providing flexibility and rigidity to a cell

• Generating electrical impulses

• Transporting bodily fluids

What are the smaller units that make up proteins?

• Sugars

• Nucleotides

• Amino acids

• Fatty acids

How are the bases in RNA represented?

• U, C, A, G

• A, T, C, G

• G, C, A, T

• A, U, C, T

What is a point mutation?

• A mutation that always results in cancer

• A mutation that has no effect on the protein

• A mutation where a base is added or deleted

• A mutation where one of the three bases is replaced with a different base

What can a point mutation sometimes create that affects the amino acid chain?

• A new cell

• A new protein

• A stop signal

• A start signal

What happens in a frameshift mutation?

• One or more bases are replaced

• One or more bases are inserted or deleted

• The entire DNA sequence is duplicated

• The protein is always rendered ineffective

How does a frameshift mutation affect the reading frame?

• It duplicates the reading frame sequence

• It corrects the reading frame sequence

• It disrupts the reading frame sequence

• It does not affect the reading frame

What can knowing all the mutations present in a tumor help with?

• Predicting the weather

• Determining the most effective treatments

• Creating new types of cancer

• Developing new types of cells
