Mutations

What are the building blocks of proteins called?

• DNA
• RNA
• Ribosomes
• Amino Acids

Any change in the sequence of DNA is...

• transgenic shift
• Single Genotype
• Monohybrid Trait
• Mutation

DNA molecule segment is : TTA CGC AAG The mutated DNA segment is TTC GCA AG. This is an example of ___ mutation.

• Substitution

• Deletion

• Insertion

• Inversion

What is a Gene?

• A segment of RNA that encodes for a protein
• A chromosome
• A segment of DNA that encodes for a protein
• Your genome

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

• no mutation
• substitution
• insertion
• deletion

This type of mutation in DNA alters just one base in a DNA sequence

• point mutation

• translocation

• inversion

• trisomy

The bottom DNA sequence in the image has been altered by this type of mutation

• substitution

• insertion

• deletion

• translocation

Which of the following would result in a frameshift mutation?

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

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 type of substitution in which one amino acid changes is called 

• Nonsense
• Missense
• Silent
• all of the above
