Inheritance And Variation Of Traits (Mitosis) Flashcards
(27 cards)
Alleles
Genes in chromosomes
Homologous
Chromosomes: Same shape and gene spot but not same alleles
Microtubules
Make up spindle fibers
Checkpoints
G1, G2, Mitosis to ensure proper division
Mutated/Mutation
A change
Regulation
To maintain normal/consistent
Binary Fission
Cell division in prokaryotes
Prokaryote
A single celled organism that has no nucleus
Autosomes/Body chromosomes
First 22 pairs (44 chromosomes in total)
Sex chromosomes
Last pair of chromosomes (2 in total)
Metabolic
All chemical reactions in body
Eukaryote
Has a nucleus and membrane bound organelles
Nucleolus
Located in nucleus and makes/synthesizes ribosomes
Plant cell
Cell wall and chloroplast
Cell plate
Forms in plants where a cleavage furrow would be in an animal cell
p53
Guardian of the genome (regulates the cell cycle)
BRCA-1
Breast cancer gene
Cancer
Disease of mutation in mitosis
Transformed
Changed
Gene
Part of the genome that codes for a specific protein or trait
Benign
Tumor cells that are at original site and usually non-cancerous
Malignant
Tumor that spreads
Metastasis
Spreading
Chemotherapy
Drugs that are designed to kill cancer but also kill good cells
