Interphase
The theory that states that all cells come from preexisting cells.
What is the Cell Theory?
The organelle where DNA replication occurs in eukaryotes.
What is the nucleus?
Non reproductive cells of the body
What are somatic cells?
Reproductive cells of the body
What are gametes?
In this phase, the chromosomes attach themselves to the spindle fibers.
What is prophase II?
The phase where DNA is replicated.
What is the S phase?
The place where DNA replication begins on the DNA strand.
What is the origin of replication.
The end result of mitosis.
What are two identical daughter cells?
The cycle in which crossing over occurs.
What is late prophase I?
The end goal/product of meiosis.
What are four genetically different cells?
The percentage of a cells life that it spends in interphase.
What is 75% to 90%?
A single long double helix of DNA wrapped around proteins called histones.
What is a chromosome?
The phase where microtubules attach to chromosomes at kinetochore.
What is prometaphase?
In this phase, the chromosomes separate to each pole.
What is anaphase I?
In this phase, a nuclear envelope forms around each haploid set of chromosomes.
What is telophase II?
The first “break” phase of interphase.
What is G2?
The enzyme that adds new nucleotides to the leading stand of a strand of DNA in a certain direction.
What is DNA polymerase?
The phase of mitosis when the the spindle apparatus begins to form.
What is prophase?
When meiosis I ends, the cells are this in terms of chromosome number.
What is haploid?
The diploid (2N) number of humans.
What is 46?
The part of the cell cycle that checks for any damages / mutations after DNA replication.
What is the G2 checkpoint?
The type of DNA strand that results in DNA polymerase attempting to make DNA on the lagging strand.
What is an Okazaki fragment?
After mitosis occurs, this occurs and finalizes the separation of the two new cells.
What is cytokinesis?
Paired homologous chromosomes line up.
What is metaphase 1?
In anaphase II, these move to the poles of the cell.
What are chromatids?
