Exam 3 Vocab Flashcards
Mitosis
The division of genetic material in the nucleus that produces daughter cells genetically identical to the parent cell
Cytokinesis
The division of the cytoplasm into 2 daughter cells
What are the phases in mitosis?
Prophase Prometaphase Metaphase Anaphase Telophase
Centriole
Cylindrical structures that compromise micro tubules
Mitotic spindle
The macromolecular machine that segregates chromosomes to two daughter cells during mitosis
Operon
A bunch of genes together that do a common job
Constitutive mutant
They are always producing the protein
Polycistronic gene
Common in bacteria, many genes are turned up or down by a single regulatory factor
Allele
Different versions of the same gene on a particular chromosome
G1 cell cycle stage
First gap stage, takes in nutrients and gets things ready for duplicating
S cell cycle stage
When they duplicate and synthesis the DNA
G2 cell cycle stage
Another gap stage, grows and takes in nutrients, leads to mitosis
Mitosis cell cycle stage
Division,split threads
