UCI Bio 93 with the Trio Final Review questions with
accurate answers
-55 mV Ans✓✓✓ Action potential threshold
-70 mV Ans✓✓✓ Resting Potential.
"Lock and Key" Ans✓✓✓ Phrase used to describe the very specific
nature of enzyme-substrate interactions.
1st Law of Thermodynamics Ans✓✓✓ Energy is constant and cannot
be created or destroyed.
2^x Ans✓✓✓ Formula to find the number of unique gametes that could
be produced through independent assortment from a genotype, where x
is the number of heterozygous genes.
2nd Law of Thermodynamics Ans✓✓✓ Every energy transformation
increases the entropy in the universe.
3' to 5' Ans✓✓✓ The direction which the template DNA strand is read
5' to 3' Ans✓✓✓ The direction in which DNA elongated
A and T Ans✓✓✓ 2 hydrogen bonds.
,Acids Ans✓✓✓ Increase the H+ concentration of the solution.
Activator Ans✓✓✓ A protein that binds to an enhancer and stimulates
transcription of a gene.
Active Transport Ans✓✓✓ Requires energy. All transport proteins that
are involved in active transport are carrier proteins.
Addition Rule Ans✓✓✓ When trying to calculate probability of more
than one mutually exclusive genetic event. Within one punnet square.
Aerobic Ans✓✓✓ A process which requires the input of oxygen.
Amino Acids Ans✓✓✓ Alpha Carbon, amino group, hydrogen,
carboxyl group, and an R group.
Amino Ans✓✓✓ H
/
N
\
H
Acts as a base. Required for Amino Acids.
,Aminoacyl-tRNA Binding Site Ans✓✓✓ The "A" site of the ribosome
is the location in which the anticodon from the tRNA is bonded to the
codon from mRNA.
Anaerobic Ans✓✓✓ A process which does not require the input of
oxygen.
Anaphase Ans✓✓✓ The phase during mitosis in which the
chromosomes are pulled apart and walk to opposite poles of the cell.
Anchorage Dependence Ans✓✓✓ The restriction that a cell must be
connected or linked to another structure. The only exception is a RBC.
Animal Pole Ans✓✓✓ Has less yolk.
Astrocytes Ans✓✓✓ Surport neurons and form the blood-brain barrier.
Atom Ans✓✓✓ The foundation of everything
ATP Ans✓✓✓ Used for mechanical, transport, and chemical work.
ATP is also an RNA nucleotide.
ATP Synthase Ans✓✓✓ Uses the process of chemiosmosis to transport
H ions through it and produce ATP by oxygen accepting the H ions to
make H2O
, Axon Hillock Ans✓✓✓ Point where the cell body of a neuron connects
to the axon.
Bacterial Transformation Ans✓✓✓ Refers to the assimilation of
external DNA into the cell.
Barr body Ans✓✓✓ A compact object that that the second X
chromosome in each cell of a female body condenses into in order to
inactive its genes.
Bases Ans✓✓✓ Decrease the H+ concentration of the solution.
Bicoid Ans✓✓✓ A maternal effect gene that affects the front half of the
body and produces the head.
Bioengernetics Ans✓✓✓ How energy flows through organisms.
Blastocoel Ans✓✓✓ Fluid filled cavity within a blastula.
Blastomeres Ans✓✓✓ The name for the many small cells produced by
cleavage petitions in the cytoplasm of one large cell.
Blastula Ans✓✓✓ A ball of cells
