DNA
T is to A as C is to?
G
What is natural selection
The process by which individuals who are able to better adapt to their environment are more likely to survive and reproduce then other members of the same species
Who is the Father of Genetics
Charles Darwin
What is a mutation?
any change in the sequence of DNA
What type of bird nest above the soccer field
Osprey
What is the matching sequence for a DNA strand that reads TTCG
AAGC
How is artificial selection different from natural selection
Artificial selection is caused by human choosing which animals to selectively breed
An animal with the Allele combination of Gg is an example of what?
Heterozygous
The three types of common mutations are?
Substitution, delection, and insertion
The highest part of a wave is called a what?
Crest
What is the structer of DNA called
Double Helix
Where do randomized traits in animals come from
mutations
Organisms that reproduce asexually generally have offspring that are?
Genetically Identical
What are some ways that the likelyhood of mutations happening are increased
Exposure to chemicals, radiations, or sertian types of diseases.
You can make the magnetic field around an electromagnet stronger by
increasing the current or number of coils
What is the process of DNA replication called
Mitosis
How does "survival of the fittest play a role in natural selection"
Animals that are more fit are able to survive and pass on their genetics vs animals that are less fit
What causes some traits to skip a generation
resessive alleles
In an insertion mutation what happens
one or more bases get added
a starfish broke of an arm and that arm grew to become a new organism. This is an example of...
fragmentation
What three compounds make up DNA?
Sugar, Phosphate, Nitrogenous Base
What is the main driving force behind natural selection
changing environments
Why does sexual reproduction result in more genetic diverseity than asexual?
In sexual reproduction the offspring receives 50% of their DNA from each parent
In a DNA strand that originally looked like this A-T-T-C-G changes to A-C-T-C-G, what has happened
Substitution
None, they are all incredible
