Mutations

What mutation has occurred here?

T-G-A-C-C-A

T-G-A-G-C-A

• Substitution

• Deletion

• Insertion

• Frameshift

Any change in the sequence of DNA is...

• transgenic shift
• Single Genotype
• Monohybrid Trait
• Mutation

ATT-TGA-GCC- Original

ATT-GAG-CC - Mutated

The example above is an example of a

• Insertion- Frameshift

• Deletion- Substitution

• Deletion -Frameshift

• All of the above

Which of the following would result in a frameshift mutation?

• Insertions only
• Substitution only
• Deletion only
• Insertions and Deletions

Are all mutations bad?

• Yes
• No
• Maybe?

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.

What do gene mutations change?

• DNA

• RNA

• Proteins

• Lipids

A permanent change in the DNA sequence

which can affect a single gene or group of genes

• Homeostasis

• Somatic Cell

• Chromosomal Mutation

• Gene Mutation

Mutations that involve parts of or all of

a chromosome

• Replication

• Deletion Mutation

• Chromosomal Mutation

• Transcription

Part of a chromosome

is deleted

• Deletion Mutation-Gene

• Translocation

• Deletion Mutation -Chromosomal

• Crossing Over
