Major Functions
This part of the cell is responsible for cellular shape and structure, and also plays a role in movement.
What is the cytoskeleton?
Microtubules are composed of this protein.
What is tubulin?
DNA
What is deoxyribonucleic acid?
These two scientists were awarded the Nobel Prize in 1962 for discovering the structure of DNA.
Who are Watson and Crick?
This component of the cytoskeleton serves as organizers of intracellular structures by anchoring organelles and vesicles and providing tracks for their movement.
What are microtubules?
Dynein and kinesin, made of this type of macromolecule, make things move along microtubule "tracks" within the cell.
What are proteins?
RNA
What is ribonucleic acid?
What are histones?
These use environmental cues to aid in water retention and water loss.
What are stomata?
Microfilaments are composed of this protein, which is also often the most common protein in the cell.
What is actin?
A & G
What are Adenine and Guanine?
What is chromatin?
This part of the cytoskeleton is responsible for binding to and exerting forces on the plasma membrane. It helps to shape the cell and help it move.
What are microfilaments?
What are nucleotides?
C & T
What are Cytosine and Thymine?
This rule states that the amount of G will always equal the amount of C, and the amount of A will always equal the amount of T.
What is Chargaff's Rule?
Keratin is a type of this component of the cytoskeleton, commonly found in skin cells as well as hair and nails. These are known to help cells withstand mechanical stress as they are durable.
What is an intermediate filament?
What are purines and pyrimidines?
U
What is uracil?
The DNA backbone is held together by this type of covalent bond.
What are phosphodiester bonds?
