Super-coiled DNA that is visible in a light microscope.
What is a chromosome?
This happens when the surface area to volume ratio gets too small in a prokaryotic cell.
What is binary fission?
The cell spends the majority of its time in this phase.
What is interphase?
Chromosomes align along the metaphase plate. They are made of identical sister chromatids.
What is metaphase?
This organelle uses an electron transport chain to make ATP in plant and animal cells.
What is a mitochondrion?
DNA that is not super-coiled. It can be transcribed.
What is chromatin?
This is the place on the bacterial chromosome where DNA attaches to the cell wall and DNA replication begins.
What is the Origin of Replication?
This is cell cycle stage that keeps a cell from replicating its DNA.
What is G0?
OR
What is quiescence?
Chromosomes line up along the metaphase plate. The sister chromatids may not be identical because of crossing over.
What is metaphase II?
This organelle is responsible for using an mRNA template to make a polypeptide.
What is a ribosome?
These are identical copies of DNA strands.
What are sister chromatids?
This allows growth and repair of damaged tissues.
What is mitosis?
This is a consequence of loss of cell cycle control.
What is tumor growth?
Tetrads lign up along the metaphase plate.
What is metaphase I?
What is this?
What is an amino acid?
These are lengths of DNA that have the same genes in the same order, but may have different alleles.
What are homologous chromosomes?
These are the ways that meiosis promotes variation in a population.
What are random orientation and crossing over?
This describes how normal cells won't proceed through mitosis if they aren't stuck to something.
What is anchorage dependence?
Centromeres of each homolog attach to spindle fibers.
What is metaphase I?
What is this?

What is alpha glucose?
This structure appears when homologous chromosomes intertwine during prophase I.
What is a chiasmata?
This is the stage of meiosis that results in haploid cells.
What is meiosis I?
OR
What is anaphase I?
These inactive enzymes are always present in the cell, and need cyclins in order to become active.
What are cyclin dependent kinases?
Centromeres of sister chromatids are attached to spindle fibers.
What are metaphase and metaphase II?
This explains how prokaryotic cells became eukaryotic cells.
What is the endosymbiotic theory?
