Nucleotide Mutations Flashcards
1
Q
What is a mutation?
A
A random change in the DNA
2
Q
What is a single gene mutation?
A
The alteration of a DNA nucleotide sequence as a result of the substitution, insertion or deletion of nucleotides
3
Q
What results in a frame-shift mutation?
A
Nucleotide insertions or deletions
4
Q
What is substitution?
A
When DNA nucleotide bases are switched for a different nucleotide base and only one amino acid is altered
5
Q
What is deletion?
A
When a DNA nucleotide base is deleted from the nucleotide sequence.
Every amino acid after point of deletion will be put out of sequence
6
Q
What is insertion?
A
When a DNA nucleotide base is added to the nucleotide sequence.
Every amino acid after point of insertion will be put out of sequence.
