DNA & Genes
What is the shape of a DNA molecule? (Two possible answers)
Twisted Ladder or Double Helix
This is an error during DNA replication that can cause changes in genetic material.
Mutation
One set of an instruction for an inherited trait
Allele
In natural selection, organisms with traits better suited to their environment are more likely to do this.
Survive and Reproduce
This type of adaptation helps an animal blend in with its environment to avoid predators.
Camoflauge
What are the four letters of the DNA Nitrogen Rich Bases
A,C,T,G
A scientist is studying bacteria. With these bacteria the scientist began to notice that these bacteria were anti-biotic resistant. Would this make them more/less likely to reproduce
more
The passing of traits from parents to offspring is called
heredity
A wildfire darkens the forest. The forest is full of light squirrels and dark squirrels. According to Natural selection, which species is most likely to survive and pass on their traits to future generations?
Dark Squirrels
This adaptation allows some desert animals to survive extreme heat by minimizing water loss and being more active at night
Being Nocturnal
What is the primary role of DNA in cells?
To store genetic information.
When studying genetic materials that affect traits, where should a scientist look?
Nucleus
