w8 Protein Sorting & Recombinant DNA / DNA replication and cell cycle

t/f are all proteins translated on the rough endoplasmic reticulum

no

nuclear envelope function

acts as the barriers around this organelle and has pores that allow molecules in/out of the organelle

Rough Endoplasmic Reticulum function

creates lipids and transmembrane and secretion proteins

smooth endoplasmic reticulum function

creates fatty acids and phospholipids

golgi apparatus functions

1. modifies proteins and lipids

2. sorts them

3. adds carbohydrates to proteins & lipids

lysosome functions

degrade macromolecules

SRP binds to

protein signal sequences (nucleotide sequences)

mitosis

division of nucleus

cytokinesis

division of whole cell

S phase

dna replication

G1 phase

regulatory proteins made that activate enzymes that synthesize dna

G2 phase

cell and protein content size increase

G0 phase

nondividing state of cells -- In btwn M-S phase

leading strand

long uninterrupted strand

lagging strand

short pieces of the DNA strand made bc it has a 5'end, but nucleotides can only be added to 3', so new short strand is made
