Symbiotic Relationships
A relationship where one organism benefits and the other is neither helped nor harmed.
commensalism?
DNA is made up of these smaller units
nucleotides
The process of making RNA from DNA
transcription
A change in the nucleotide sequence of DNA
mutation
The slow, steady change in horse species’ size and tooth structure over millions of years is an example of this evolutionary pattern
gradualism
A close relationship where both organisms benefit
mutualism
The complementary base for adenine in DNA
thymine
The process of making a protein from mRNA.
translation
This type of mutation involves the substitution of one base for another
point mutation
A species of jellyfish has remained almost unchanged for hundreds of millions of years. This lack of significant change is called
stasis
relationship in which one organism benefits and the other is harmed
parasitism
The Ladders of DNA is made up of
Sugar Phosphate
The molecule that brings amino acids to the ribosome
The molecule that brings amino acids to the ribosome
A mutation that shifts the reading frame of the codons.
frameshift mutation
: Fossil records of the Cambrian explosion, showing sudden appearances of many new species, illustrate this model of evolution
punctuated equilibrium
Name an example of mutualism between plants and animals
bees pollinating flowers
DNA is stored in this organelle in eukaryotic cells.
nucleus
The three-base sequence on mRNA that codes for an amino acid
codon
Mutations in gametes can be passed on to offspring. These are called
germline mutations
The sudden emergence of modern mammals after the extinction of dinosaurs is an example of
punctuated equilibrium
The remora fish attaches to sharks to get food and transportation. What type of symbiosis is this
commensalism
During DNA replication, this type of bond is broken between bases to separate the strands.
hydrogen bonds
The location in the cell where translation occurs.
ribosome
Exposure to chemicals or radiation that causes mutations is known as
mutagen
Over millions of years, small changes in finch beak shapes allowed them to adapt to different food sources in the Galapagos Islands. This gradual adaptation is an example of
gradualism
