TEST 5 BIOL 1408 Flashcards
What is a Frameshift mutation?
insertion/deletion of a base, changing the reading frame
What is vestigial trait?
features we inherited from ancestors, but no longer have any function
What is a neutral mutation?
substitution of a base, but doesn’t change the function of the protein
What is a anatomical homology?
similarities in bone structure, and example is wing of bat/forearm of person
What does Uracil pair with?
Adenine
What is the order of Linnean Classification?
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
What is DNA?
deoxyribose, double helix, ATCG, can’t leave nucleus
What is RNA?
ribose, single-stranded, AUCG, can leave nucleus
What is a start codon?
sets the reading frame, AUG
What is stop codon?
stops protein synthesis, UAA, UGA, UAG
What is rBGH used for?
inserted into cows to increase milk production
How do fossils prove evolution?
provides a record of how species have evolved over time
What is transcription?
DNA –> RNA, occurs in the nucleus
What is translation?
RNA –> Protein, occurs in ribosomes
What is Aureus?

Do you need two DNA strands for transcription?
FALSE (only one)
Why is it that fossils that are deeper older?
sedimentation
What is microevolution?
changes that occur within a biological population
What are 3 ways to see evolution?
all of the above
Where is codon found?
mRNA
Where is anti-codon found?
tRNA
What does regulating gene expression do?
controls the amount of proteins produced
What is biogeography?
distribution of species on earth
Is nRNA real?
NO
What does tRNA do?
transfers RNA
What does mRNA do?
messenger RNA that contains the instructions
