What is a GMO?
An organism that has had its DNA modified by humans
An organism missing a chromosome
Epigenetics
A genetically identical organism
"transgenic" refers to an animal that:
Has DNA from another organism spliced into its genome
Has undergone DNA modification
Has unique genes for its species
Which is an example of SELECTIVE BREEDING ?
(also called artificial selection)
A giraffe’s long neck.
Training a horse to run faster.
Clipping a horse’s tail so it is not too long.
Cross breeding a labrador retriever with a poodle.
so the offspring will inherit the best traits from both parents:
One problem with selective breeding is
creating a new species
gene variety is lost
extinction of a species
What is Inbreeding
When two closely related animals are bred together
When two none related animals are bred together
When animals are allowed to chose their own mates
When humans choose which animals will mate together
What was the significance of Dolly the Sheep?
She was the first organism ever cloned
She was the first clone created from an adult animal
She was the first animal cloned as an embryo
She was the first animal to be cloned multiple times
What is a gene
a section of DNA that codes for a trait
a pair of pants that are made of denim
the whole entire chromosome found in the nucleus
What is a genetic mutation
the making of a zombie
any change in the DNA base pairs
the process of duplicating the DNA in a cell
A substitution mutation occurs when
a base pair is missing from the DNA strand
a base pair is added to the DNA strand
a base pair is replaced with a different base pair
An insertion/additon mutation occurs when
a base pair is missing from the DNA strand
a base pair is added to the DNA strand
a base pair is replaced with a different base pair
A deletion mutation occurs when
a base pair is missing from the DNA strand
a base pair is added to the DNA strand
a base pair is replaced with a different base pair
