Mutations

Any change in the sequence of DNA is...

• transgenic shift
• Single Genotype
• Monohybrid Trait
• Mutation

In which molecules can genetic mutations occur?

• Proteins and Lipids

• DNA and Proteins

• DNA and RNA

• Carbohydrates and Lipids

Why are insertion and deletion mutations so harmful?

• They change all of the codons from the mutation on down the line, which changes the amino acid sequence
• They insert things that an organism doesn't need.
• They often delete things that organisms need.
• Insertion and deletions are not any more harmful than substitution mutations.

DNA molecule segment is : TTACGCAAG
The mutated DNA segment is TTCGCAAG. This is an example of ___ mutation.

• Substitution
• Deletion
• Insertion
• Inversion

Grace, Abigail, and David are studying genetics. They come across two DNA sequences. The normal sequence is GAG-CTC-GAC-AGA and the mutant sequence is GAG-CTC-CAC-AGA. They are trying to identify the type of mutation. What type of mutation is it?

• no mutation

• substitution

• insertion

• deletion

Do all genetic mutations have negative effects?

• True

• False

What are the three types of gene mutation?

• Insertion, Deletion, Subsitution

• Aberration, Deletion, Substitution

• Inversion, Duplication, Insertion

• Insertion, Duplication, Substitution
