What is the most common mechanism for repairing damage to DNA?
Nucleotide excision repair
What will happen if our DNA is incorrectly paired?
Incorrectly paired nucleotides cause deformities in the secondary structure of the final DNA molecule. During mismatch repair, enzymes recognize and fix these deformities by removing the incorrectly paired nucleotide and replacing it with the correct nucleotide.
What enzyme proofreads the copy of DNA looking for errors during replication?

What diseases can gene editing fix?
7 Diseases CRISPR Technology Could CureCancer. The first applications of CRISPR could be in cancer. Blood disorders. Blindness. AIDS. Cystic fibrosis. Muscular dystrophy. Huntington’s disease.
Why do we need gene editing?
Genome editing technologies enable scientists to make changes to DNA, leading to changes in physical traits, like eye color, and disease risk. Scientists use different technologies to do this. These technologies act like scissors, cutting the DNA at a specific spot.
What are the two types of genetic mutations?
There are three types of DNA Mutations: base substitutions, deletions and insertions. Single base substitutions are called point mutations, recall the point mutation Glu —–> Val which causes sickle-cell disease.
Which type of mutation causes the most damage?
Deletion mutations, on the other hand, are opposite types of point mutations. They involve the removal of a base pair. Both of these mutations lead to the creation of the most dangerous type of point mutations of them all: the frameshift mutation.
