Gene
Adenine; thymine; guanine; cytosine
nucleotides that make up DNA
mRNA
messenger RNA; forms in the nucleus and leaves via pores
fixity
commonly held idea that species were specially created
South America
The area where Darwin spent the most time studying
Allele
Different information for a trait.
Rosalind Franklin
discovered that DNA was a double helix
initiation, elongation and termination stage
The stages of transcription of DNA to RNA and translation of RNA to a protein.
Naturalist and companion to the captain
Evolution
genetic changes to a species over a long period of time
Aa
heterozygous
Semi-conservative replication
parental strand serves as template for daughter strand
Introns
noncoding sequences of RNA that get cut out
Catastrophism
local catastrophes cause local organisms to go extinct; repopulated by species from surrounding areas
Natural selection
The mechanism of evolution; caused by environmental selection
Polygenetic
a trait that is influenced by two or more sets of alleles
Transcription
The process of gene flow from DNA to RNA
tRNA
carries aa on one end and anti-codon on the other
organisms adapt to the environment in their life times and pass the trait on to their offspring. Lamarck.
Artificial selection
Humans selecting and breeding for particular traits
X-linked alleles
traits that are only associated with the female X chromosome.
Translation
The flow of information from RNA to a protein
triplet code
3 base code words that code for an aa
Uniformitarianism
Earth is subject to slow but continuous cycles
Biochemical evidence
evidence of evolution that is tied to DNA triplet code and aa, and nucleotides
