Lab 3
Cell cycle is divided into what four main phases?
G1, S, G2, and M.
Lab 3
What phases in the cell cycle are interphase?
G1, S, G2,
Lab 3
Growth and normal metabolic roles
-
G1
Lab 3
A phase when a cell makes (synthesizes) a duplicate copy its nuclear DNA.
S phase
Lab 3
Cell double checks duplicated chromosomes for error
-makes an any needed repairs
G2 Phase
Lab 3
Rough ER
Smooth ER
**Rough ER:
**protein production by ribosomes
Smooth ER:
synthesis, transport, and storage of lipids
carbohydrate metabolism
detoxification of drugs and poisons**
Rough- Ribo
Smooth- skin, skin is fat, fat=lipid, fat= eating CARBS (Ca
a system of interconnected channels called cisternae
Endoplasmic reticulum (ER)
The site for protein synthesis.
Ribosomes
What lacks ribosomes?
Smooth ER
A package of enzymes
Lysosomes
double unit membraned organelles specialized for synthesizing ATP
Mitochondira
folds of inner membrane of mitochondria
Cristae
Which phase of the cell cycle is DNA replicated?
S Phase
Centromeres divide in two. Spindle fibers pull sister chromatids apart to opposite poles.
Anaphase
Chromosomes condense. Nuclear membrane disappears. Centrioles migrate to opposite sides.
Prophase
Chromosomes align in midline. Spindle fibers attach to kinetochores. Aster fibers attach to plasma membrane.
Metaphase
Chromosomes gather at each pole. Chromatin disappears. Nuclear membranes appear. Mitotic spindles vanish.
