Acronyms
Known to have 3 phosphate groups and an Adenine, this molecule goes by adenosine triphosphate.
What is ATP?
Apoptosis is often execulted by this, bringing the end of a cell's life.
What are Lysosomes?
Meselson & Stahl discovered this model that states that as DNA replicates, one-half of the previous generation is kept and the other half is added.
What is the Semi conservative Model?
The Harmone-Receptor compelx enters through this to the nucleus, often carrying hormones like testosterone.
What is a nuclear pore?
Catabolic pathways are when energy is released and complex molecules are broken down, as done by all organisms in this process.
What is cellular respiration?
What is the Promoter Region?
The Calvin Cycle had three stages; carbon fixation, reduction, and this step.
What is regeneration?
The equation for the change in free energy was discovered by this scientist, and then used to calculate exergonic and endergonic reactions.
Who is J. Willard Gibbs?
HELA cells have these, which are never-ending, on the ends of their chromosomes ensuring that the condensed DNA isn't cut off with every replication cycle.
What are telomeres?
Rickets disease is a direct product of the lack of this, often found in individuals who have darker skin and are living in more overcast climates.
What is Vitamin D?
cAMP is the acronym for this second messenger that plays an important role in the signal transduction pathways.
What is Cyclic AMP?
In charge of regulation, this is an enzyme that activates or deactivates proteins in the cell cycle by phosphorylating them.
What is cyclin-dependent kinase?
The central dogma of DNA was coined by this scientist who also worked on the double helix model.
Who is Francis Crick?
Occurring when the nucleus diappears, this is when DNA condenses into chromosomes and spindle fibers gain access to the genetic material.
What is prophase/prometaphase?
This type of active transport is an example of when the cell expends ATP to move things against the concentration gradient.
What is a sodium-potassium pump?
Used in the light reactions, this part of the cycle is responsible for the electron passage through photosystems 1 & 2.
What is the PEA (primary electron acceptor)?
This cycle operates with a set of enzymes that organize metabolic pathways, the end product acting as the activator.
What is enzyme localization?
In his experiment, Hershey and Chase used this to demonstrate genetic transformation due to the assimilation of external DNA in the cell.
What is a bacteriophage?
This type of evolution occurs when two different species are under the same selective pressures and so they evolve to have similar traits and look similar.
What is parallel evolution?
RNA splicing uses these to take out large sections of RNA.
What are? SNRPs
When too much apoptosis occurs, a function that allows the control of cell cycle death, people contract this disease.
What is Parkinson's disease?
Using this protein to support the condensation of DNA, chromosomes are created from DNA wound around them.
What are histones?
The process of crossing over and creating recombinant chromosomes typically happens in this location.
What is the chiasma?
