CELL CYCLE

SPINDLES BEGINS TO FORM

NUCLEOLI DISAPPEAR

SISTR CHROMATIDS JOIN

(BUNCH OF WORMS)

NUCLEAR MEMBRANE DISSOLVES

KINETOCHORES ATTACH TO SPINDLE

KINETOCHORES ATTACHED TO SPINDLE FIBERS

CHROMOSOMES BEGIN TO ALIGN DOWN CENTER OF CELL

KINETOCHORE MICROTUBLES SEPERATE CROMOSOMES TO OPPOSITE POLE

OCCURS DURING/AFTER TELOPHASE

DIVISION OF CYTOPLASM

ANIMAL: CELL CLEAVAGE

PLAN:CELL PLATE DEVELOPS IN ORDER TO DIVIDE CYTOPLASM

BIRTH NEW CELLS

OCCURS MORE OFTEN IN CELLULAR LEVEL

MULTIPLE STEP CALLED MITOSIS

TISSUE RENEWAL

GROWTH/DEVELOPEMENT

REPRODUCTION

accounts for 90% of the cycle. copies its chromosomes and prepares for cell division

GAP 1 PERIOD AFTER MITOSIS/BEFORE THE BEGINNING OF DNA SYNTHESIS

PREPARATIONS FOR COPING DNA

SYNTHESIS TIME WHEN THE CELLS DNA IS REPLICATED

G2 IS TIME AFTER S AND PRIOR TO MITOSIS

CELL DOUBLES IN SIZES/DOUBLES AMOUNT OF CYTOPLASM AND ORGANELLES

STAGE BEFORE DNA REPLICATION

CELLSARE ARRESTED IN A NON DIVIDING STAGE

GENOME COMPLETE SET ORGANISMS GENES

LOCATED ON CHROMOSOMES CELLS NUCLEUS

CONTAIN GENETIC MATERIAL

MADE OF CROMATIN (COMBINATION OF DNA& PROTEIN ELLS

NOT VISIVLE IN A CELL UNTIL CELL DIVISION

HUMAN SOMATIC CELLS 46 CHROMOSOMES (DIPLOID CELLS)

HUMAN GAMETES(EGG/SPERM) 23 CHROMOSOMES (HAPLOID CELLS)

SINGLE DOUBLE STRANDED MOLECULE DNA

TO REPLICATE DNA MUST BE TIGHLY WOUND INTO CHROMOSOMES

COILDS AROUND A 8 HISTONES PROTEINS TO FORM A NUCLEOSOME ->COIL FURTHER INTO SUPERCOILS

HISTONE PROTEINS ARE +CHARGED ATTRACT THEM TO PHOSPHATE GROUPS OF DNA NEGATIVELY CHARGED

A PINCHED REGION IN A CHROMOSOME

CONTAINS SPECIC DNA BOUND TO A DISK PROTEIN KINETOCHORE

• PROPHASE
• PROMETAPHASE
• METAPHASE
• ANAPHASE
• TELOPHASE & CYTOKINESIS

NUCLEOLUS FORMING

CLEVAGE BURROW

NUCLEAR ENVELOPE FORMING

INTERPHASE

METAPHASE

ANAPHASE

TELOPHASE & CYTOKINESIS

PROMETAPHASE

PROMETAPHASE

GENETIC INFORMATION

ENTIRE COMPLEX OF DNA AND PROTEIN THAT IS THE BUILDING MATERIAL

JOINED COPIES OF ORIGINAL CHROMOSOME

IDEANTICAL A MOLECULRE

BEGINS TO FORM IN THE CYTOPLASM DURING PHASE

A SUBCELLULAR REGION CONTAINING MATERIAL THAT FUNCTIONS THRUGHOUT THE CELL TO ORGANIZE THE CELL MICROTUBULES

A RADIAL ARRAY OF SHORT MICROTUBULES EXTENDS FROM EACH CENTROME

STRUCTURE OF PROTEINS ASSOCIATED WITH SPECIFIC SECTIONS OF CHROMOSOMAL DNA
