SI Week 2 Flashcards
RNA v DNA
RNA
- single strand
- uracil, A, G, C
- ribose sugar
DNA
- double stranded
- Thymine, A, G, C
- deoxyribose sugar
DNA double Helix Components
- 5’ end is phophate group
- 3’ end is pentose sugar
- A-T (2 H+ bonds) and G-C (3 H+ bonds)
- purine (Pure As Gold)= longer, Adenine and Guanine
- pyrimidine (Cut The Pye) = shorter, Cytosine and Thymine
Definitions
- Magnification
- Resolution
- Immunocytochemistry
- Magnification: Ratio of the size of the image
of an object to its actual size - Resolution: Minimum distance between 2
points that can be differentiated - Immunocytochemistry: Using antibodies and
fluorescent molecules to detect
specific proteins in a cell

3 animal cell organelles not found in plants
flagellum, centrosome, lysosome
Plasma Membrane Functions
- structural
- transport functions
- defines cell
Nucleus Function
location of DNA
information storage, processing, and
execution
Endoplasmic Reticulum (ER) Function
- rough= modify and synthesize proteins
- many membranes folding and separate from cytoplasm
Golgi Apparatus Function
protein maturation
Ribosome Function
where mRNA first starts translating to proteins
Cytoskeleton Function
rigidity, structural
transport functions
Centrosome Function
- involved with cell division
- modification of microtubules
mitochondria function
energy metabolism
- synthesizes ATP
Flagellum Function
cell motility
Microvilli Function
increase cell’s SA for better uptake from extracellular membrane
Lysosome Function
garbage disposal
Central Vacuole (plant) Function
control H2O balance
Cell Wall (plant) Function
structure and strength
Plasmodesmata (plant) Function
communication b/w adjacent cells
Chloroplast Function
photosynthesis (energy metabolism)
Lipid Function
energy storage
Polysaccharide Granules (starch & glycogen) Function
energy storage
Endomembrane System Function
protein, carb, and lipid biosynthesis
