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

Original DNA: CAT GAT CCA

New DNA: CAT TGA TCC A

What mutation occurred?

• deletion

• substitution

• tranverse

• insertion

Which of the following would result in a frameshift mutation?

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

Mutated DNA sequences that can be passed from parent to offspring --

• occur in somatic cells (body cells)
• occur in gametic cells (sex cells)
• are rejected by meiosis
• only occur if the parent is exposed to harmful substances

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.

A mutation in which only one nucleotide is altered is called a:

• Frameshift Mutation

• Deletion Mutation

• Point Mutation

• Insertion Mutation

a change in one DNA triplet that may result in a new triplet that codes for a stop codon instead of an amino acid is known as

• missense
• nonsense
• frameshift
• silent

A type of substitution in which no  amino acids change is called 

• Missense
• Nonsense
• Silent
• Deletion
