Mutations

Any change in the sequence of DNA is...

• transgenic shift
• Single Genotype
• Monohybrid Trait
• Mutation

Where do mutations occur?

• DNA and RNA
• DNA 
• RNA
• mRNA and tRNA

Mutations affect the ________ of a protein. Because of this the proteins ______ is affected as well. 

• gene, function 
• sequence, gene
• shape,function

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

Normal-
GAG-CTC-GAC-AGA
Mutant
GAG CTC-CAC-AGA

• no mutation
• substitution
• insertion
• deletion

What are the three types of gene mutation?

• Insertion, Deletion, Subsitution

• Aberration, Deletion, Substitution

• Inversion, Duplication, Insertion

• Insertion, Duplication, Substitution

When do genetic mutations get passed from parent to offspring?

• When the Gametes (sex cells) are mutated

• When the mutation changes the order of DNA

• When the mutation occurs randomly

This is considered the most harmful type of gene mutation. It occurs when the codon reading frame is shifted and creates a chain reaction of errors in amino acids.

• Duplication

• Frameshift

• Insertion

• Deletion

Which type of mutation is shown here?

• Gene deletion

• Chromosomal deletion

• Gene insertion

• Chromosomal duplication
