Cell cycle Flashcards
What are the 3 phases of interphase
- G1
- S
- G2
State stages of mitosis
Interphase
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis (only in animal cell)
Chromosomes
Structure in nucleus containing DNA
Centromere
Reigon holding two sister chromatids together
Centriole
Organelles that migrate during mitosis and produce spindle fibres
Spindle fibre
Microtrotubles that attach to centromere and move chromosomes
Chromatin
Uncoiled DNA in a nucleus
Form of DNA before it condenses into chromosones
Why do cells divide?
-Growth of an organism
-Repair of tissues and organs
-Maintenance to replace dead cells
-Natural aging or cell death (apoptosis)
What are the 3 parts that make up NUCLEOTIDE
Phosphate group (PO4)
Pentose sugar (5 carbon sugar)
Nitrogenous base
Gene
A section of DNA that codes for a protein
Genome
All genetic material in an organism
Sister chromatids
Two identical copies of same chromosomes
Base pairs
Complementary pairs of nitrogenous bases
TRUE OR FALSE
C always binds with A
G always binds with T
FALSE
Cars goes in Garages
Apples goes on Trees
TRUE OR FALSE
Organisms with more DNA are more complex
FALSE
Traits
Features in an organism that are determined by genes
Alleles
Variations of a trait
