What are Genetic Mutations?
Can genetic mutations be good, bad, or either
They can be good or bad
What can they change
Some mutations change the way you act, live, or look
What are all the different types of DNA mutations
Substitution, Deletion, Insertion, and Frameshift
What is natural selection (simple)
Natural selection is the process through which populations of living organisms adapt and change.
Genetic mutation - what is it
An alteration/change in the bases of one or more genes or in the structure of one or more chromosomes
How can they happen
Mutations can happen from cell division, virus infection, or from something you can eat or drink
What is substitution
Substitution is when the wrong bases are matched.
Organisms that are more adapted to their environment are more likely or less likely to survive and pass on the genes that helped them survive. Which one?
More likely
What do they effect
They can disrupt normal development or cause a medical condition
What part of DNA is different when there is a mutation?
The Bases
What is deletion
Deletion is when a base is removed
Are mutations inherited?
Species evolve because some mutations are inherited, so when one animal gets a mutation it can be passed down.
_________ are used to predict the amino acids for proteins.
Nucleotide sequences/bases
Why does DNA mutation occur?
Because of mistakes when the DNA is copied.
What is insertion
Insertion is when an extra base or bases is added in and it is dangerous
What kind of mutations are usually inherited?
Good mutations
Some cases of mutation could be so severe that...
They prevent an embryo from surviving till birth
What example did we give in our slides about a good mutation?
An mutation altering the size of the beak on a bird.
What is frameshift
Frameshift is when one base is affected and it changes the res
Natural selection is apart of ______
evolution
