Inheritance And Variation Of Traits (Mitosis) Flashcards
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
Radiation
Type of treatment (for cancer)
Nucleotides
Monomer or nucleic acids
Apoptosis
Programmed death
