gene mutation Flashcards
1

A
height, hair colour, skin colour, eye colour
2
Q
what is mutation?
A
any change in the DNA sequence
3
Q
what are some potential applications of mapping human genomes
A
search for genes linked to different types of disease, understand inherited disorders, trace human migration patterns from the past
4
Q
how can mutation affect protein?
A
can cause a change in protein by changing a gene’s instructions for making a protein. a variant can cause a protein to malfunction or not to be produced at all
