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
