100
DNA stands for
What is Deoxyribonucleic Acid
100
Which bases pairs up with Adenine in RNA
What is uracil
100
Comparing the embryonic development of different animals helps to determine evolutionary relationships in nature
What is embryological origins
100
It is the movement of individuals and the gene’s that they carry from one population to another
What is gene flow
100
When an unrelated organisms evolve similarities when adapting to similar environment.
What is convergent evolution
200
This is the subunit of DNA
What is a nucleotide
200
This type of sugar is found in RNA but not DNA
What is a ribose sugar
200
We can test this to see differences between one species and another
What is DNA
200
The process by which environmental conditions determine what characteristics of a species are favorable traits
What is natural selection
200
Organisms with different ancestry begin to share ______________ traits because of their shared environment.
What are analogous traits
300
The attraction between bases is called
Complementary base pairing
300
This type of RNA carries the information from the DNA to the ribosome
What is mRNA
300
Some parts in or on an organism's body no longer have any apparent use.
What is a vestigial structure
300
Is the random loss of genes in a population that can have positive, negative or neutral effects
What is genetic drift
300
Structures that come from a common ancestor but they do not necessarily have the same function
What are homologous structures
400
DNA replication is called this because some of the parent strand is still present in the new/daughter strand
What is semiconservative
400
The process where a molecule of DNA is used as a template to form a complementary strand of RNA which can then leave the nucleus
What is transcription
400
These tell us how species have changed across long periods of the Earth’s history
What are fossils
400
this is a spontaneous switching of a nucleotide sequence in the DNA of an organism
What is a mutation
400
When a species diverges over time into two different species, resulting in species becoming less like the original one.
What is divergent evolution
500
These type of bonds join complementary bases together
What are hydrogen bonds
500
The process where the mRNA message is read at the ribosome and the protein chain is formed
What is translation
500
organs and structures that have different origin but same functions
What are analogous structures
500
Asbestos, x-rays, gamma rays and ultraviolet light are examples of this
What is a mutagen
500
The streamline shape of a killer whale, great white shark and barracuda are examples of this
What is convergent evolution
