Mutations Flashcards
1
Q
Frameshift Mutations
A
Caused by an insertion or deletion of bases in the DNA sequence
2
Q
Mutagen
A
External Influences
3
Q
Point Mutation
A
caused by a substitution of one base for another in the DNA sequence
4
Q
Insertion
A
one chuck is taken out and inserted in another
5
Q
Carcinogens
A
cancer-causing mutagens
6
Q
Silent Mutation
A
DNA Changes result in an mRNA codon that codes for the same amino acid (doesn’t affect us)
7
Q
Deletion
A
one chunk is deleted
8
Q
Somatic Mutations
A
can’t be passed down
9
Q
Missense Mutations
A
DNA change results in an mRNA codon that codes for a different amino acid
10
Q
Chromosomal Mutation
A
mutations that affect a large part of a chromosome
11
Q
Germ-Line Mutation
A
will be passed down
12
