Meiosis
|
|
|
A process by which the eukaryotic cell's endo-membrane system evolved from inward folds of the plasma membrane of a prokaryotic cell
|
Membrane infolding
|
|
|
The type of ribonucleic acid that encodes genetic information from DNA and conveys it to ribosomes, where the information is translated into amino acid sequences

|
The second stage of mitosis, all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle
|
Metaphase
|
|
|
The spread of cancer cells beyond their original site

|
|
An organelle in eukaryotic cells where cellular respriation occurs, enclosed by two concentric membranes it is where most of the cell's ATP is made
|
Mitochondrion
|
|
|
The division of a single nucleus into two genetically identical daughter nuclei makes up the mitotic phase of the cell cycle
|
Mitosis
|
|
|
The part of the cell cycle when mitosis divides the nucleus and distributes its chromosomes to the daughter nuclei and cytokinesis divides the cytoplasm, producing two daughter cells

Mitotic phase
|
|
|
A spindle-shaped structure formed of microtubules and associated proteins that is involved in the movement of chromosomes during mitosis and meiosis
