Mutations and DNA

A change in a gene, group of genes or chromosome that results in a change in the proteins

• Replication

• Mutations

• Translation

• Transcription

One nucleotide base is changed so only one amino acid

is affected

• Substitution Mutation

• Point Mutation

• Translocation

• Inverse Mutation

A nucleotide base is inserted or deleted shifting the entire DNA sequence. Entire protein will be changed.

• Substitution Mutation

• Silent Mutation

• Frameshift Mutation

• Translocation

A frameshift mutation where a nucleotide base

is removed from the DNA sequence.

• Deletion Mutation

• Substitution Mutation

• Translocation

• Silent Mutation

This type of substitution codes for a stop codon

• Missense
• Nonsense
• Silent
• Deletion

If you are missing or have an extra base  at the end of your mutated DNA . What type of mutation occurred?

• Substitution
• Frameshift
• Duplication 
• Insertion

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

• Missense
• Nonsense
• Silent
• Deletion

Which of the following would result in a frameshift mutation?

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

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

• Substitution
• Deletion
• Insertion
• Inversion

mRNA is read in chunks of three, called...

• quadralets
• anticodons
• codons
• capsids
