Chapter 8. Cell Reproduction. In a eukaryotic cell, one of the structures in the nucleus that is made up of DNA and protein; in a prokaryotic cell, the main ring of DNA. Chromosome. A type of protein molecule found in the chromosomes of eukaryotic cells but not prokaryotic cells. Histone.
The material that makes up both mitotic and interphase chromosomes; a complex of proteins and DNA strands that are loosely coiled such that translation and transcription can occur
A micrograph of the array of chromosomes visible in a cell during metaphase; a graphical display that shows an individual’s chromosomes arranged in homologous pairs and in order of diminishing size
In eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of cellular respiration, which produces ATP
Reproduction that does not involve the union of games and in which a single parent produces offspring that are genetically identical to the parent
A process in cell division during which the number of chromosomes decreases to half the original number by two divisions of the nucleus, which results in the production of sex cells (gametes or spores)
The first stage of mitosis and meiosis in cell division; characterized by the condensation of the chromosomes and the dissolution of the nuclear envelope
