Mutation and Protein Production Quiz

What is a point mutation?

• A change in multiple nucleotide bases in the DNA sequence

• A change in the order of the DNA sequence

• A change in the number of chromosomes in the DNA sequence

• A change in a single nucleotide base in the DNA sequence

How does a frameshift mutation affect protein production?

• It causes a shift in the reading frame of the genetic code, leading to a completely different sequence of amino acids in the protein.

• It leads to the production of a shorter protein

• It only affects the shape of the protein

• It has no effect on protein production

What is an insertion mutation?

• A type of mutation where a nucleotide is removed from the DNA sequence

• A type of mutation that does not affect the DNA sequence

• A type of mutation where an extra nucleotide is inserted into the DNA sequence

• A type of mutation that only occurs in RNA

How does a deletion mutation affect protein production?

• It has no effect on protein production

• It causes a frameshift mutation, leading to the production of a non-functional or altered protein.

• It increases the production of functional protein

• It leads to the production of a completely different protein

Which type of mutation causes a shift in the reading frame?

• Silent mutation

• Point mutation

• Nonsense mutation

• Frameshift mutation

What is the result of a frameshift mutation?

• A frameshift mutation results in no change to the genetic code

• A frameshift mutation causes a duplication of the genetic code

• A frameshift mutation leads to the deletion of the genetic code

• A frameshift mutation causes a shift in the reading frame of the genetic code.

How does a point mutation affect protein production?

• It decreases the rate of protein synthesis.

• It increases the stability of the protein structure.

• It can change the sequence of amino acids in the protein.

• It has no effect on protein production.

What is the main difference between insertion and deletion mutations?

• Insertion mutation changes the DNA sequence, while deletion mutation does not

• Deletion mutation adds nucleotides

• Insertion mutation removes nucleotides

• Insertion mutation adds nucleotides, while deletion mutation removes nucleotides.

Which type of mutation involves the addition of nucleotides?

• Frameshift mutation

• Insertion mutation

• Deletion mutation

• Substitution mutation

How do mutations affect the proteins produced?

• Mutations can alter the amino acid sequence of a protein.

• Mutations can only affect the shape of the protein

• Mutations always improve the function of the protein

• Mutations have no effect on the proteins produced
