Genetic Mutations Quiz

In a DNA analysis experiment, Daniel noticed that a base was missing from the DNA sequence of a sample. What type of mutation does this scenario describe?

• Insertion

• Deletion

• Substitution

• Inversion

In a biology class, Alexander is studying genetic mutations and learns that if a substitution mutation does not change the amino acid, it has a specific name. What is this mutation called?

• Missense mutation

• Nonsense mutation

• Silent mutation

• Frameshift mutation

During a genetic engineering experiment, Sophia introduces a frameshift mutation into a bacterial genome. What is the result of this mutation?

• The amino acid sequence remains unchanged.

• Only one amino acid in the sequence is changed.

• The reading "frame" changes, altering the amino acid sequence.

• The mutation results in a stop codon.

During a biology exam, Aarav is asked to identify the type of mutation in a DNA sequence where a substitution changes the amino acid to a "stop". What is his correct answer?

• Silent mutation

• Missense mutation

• Nonsense mutation

• Frameshift mutation

During a genetics lab, Samuel discovers that an extra base was inserted into a DNA sequence he was analyzing. Which type of mutation has occurred?

• Deletion

• Insertion

• Substitution

• Duplication

In a study on pea plants, Charlotte observed a new variation in the height trait. Which type of mutation is responsible for this new variation?

• Silent mutation

• Missense mutation

• Nonsense mutation

• Frameshift mutation

In the process of developing a new medication, Alexander notices that one of the synthesized proteins has an abnormal amino acid sequence. Which type of mutation is most likely responsible for this?

• Silent mutation

• Missense mutation

• Nonsense mutation

• Frameshift mutation

In a biology class, Olivia is studying genetic mutations and learns about a specific type of mutation that stops the translation of the mRNA. Which mutation is it?

• Silent mutation

• Missense mutation

• Nonsense mutation

• Frameshift mutation

Imagine Owen is a biologist studying genetic mutations. He discovers that a mutation in the gene coding for part of the hemoglobin molecule results in sickle cell anemia. What is the outcome of this mutation?

In a biology class, Benjamin is learning about the structure of DNA. He is curious to know, what is the sugar component of DNA?

• Ribose

• Deoxyribose

• Glucose

• Fructose
