Cell Communications
This type of signaling occurs between cells over long distances.
What is Endocrine Signaling?
Basic energy currency of the cell. Produced by the mitochondria and glycolysis.
What is ATP?
This prevents the transcription of an operon.
What is a repressor?
When a pure red rose is mixed with a pure white rose, the result was a pink rose. This is an example of...
What is incomplete dominance?
The condition that causes new species to emerge.
What is isolation?
This molecule binds to cell receptors to initiate a signal.
This type of reaction puts out energy into the environment, resulting in a -ΔG.
What is an exergonic reaction?
Some traits appear rarely in females but more commonly in males. This is explained by...
What are X-linked traits?
This law of heredity is proven when a dihybrid cross produces a 9:3:3:1 ratio of offspring.
What is the Law of Independent Assortment?
The inheritance of adaptations, resulting in changes to a population over time.
What is evolution?
The type of receptors testosterone and other nonpolar signaling molecules bind to.
What are intracellular (cytoplasmic) receptors?
The products of light-dependent reactions.
What are Oxygen, NADPH, and ATP?
An autosomal genetic disorder caused by nondisjunction of chromosome 21.
This method is used to determine the genotype of the unknown individual by crossing it with a homozygous recessive individual.
What is a test cross?
One of two drivers of evolution. This happens by chance.
What is genetic drift?
The reason a signaling cascade is used in cell communications.
What is amplification of a signal?
C4 photosynthesis avoids this type of metabolism dead-end by sequestering CO2 as an acid.
What is photorespiration?
A simple type of gene regulation is this, which turns off transcription when the desired products are high in concentration.
What is a feedback mechanism?
The best explanation for why some traits are often inherited together.
What is are linked genes?
The reason that consumers do not eat up all of the producers on the planet.
What is limitation by density-dependent factors? (Predation)
Maturation promotion factor, or MPF, signals the cell to proceed into the M phase. Its activity must depend on this type of protein.
What are cyclins?
The folds of the cristae in a mitochondrion create the surfaces needed for this metabolic process to create ATP from ADP.
What is oxidative phosphorylation?
This biotechnology allows the rapid replication and amplification of DNA or RNA fragments.
What is PCR?
The principle of heredity would explain a dihybrid cross resulting in a ratio other than 9:3:3:1.
What is recombination? (crossing over)
The transitional areas between biomes.
What are ecotones?
