Honors Biology: The Cell Cycle

Flashcards for Honors Biology Cell Cycle Review

Where does DNA replication occur in the cell cycle?

DNA is replicated during cell division and not during the G1 phase of interphase.

What is the result of both binary fission and mitosis?

Both binary fission and mitosis are asexual forms of cellular reproduction.

What type of cells do binary fission and mitosis result in?

Both binary fission and mitosis result in diploid daughter cells.

How many chromosomes are in human cells, and how are they organized?

Human cells have 46 chromosomes in 23 homologous pairs.

What are Chiasmata?

Chiasmata are touchpoints between sister chromatids that form during the late prophase I stage of meiosis.

When do chromosomes replicate during meiosis?

Chromosomes replicate prior to prophase I, but not before prophase II.

What is monosomy?

Monosomy is a condition in which a cell receives one too few chromosomes during meiosis.

What is the definition of a Zygote?

A zygote is a diploid daughter cell formed when the male and female gametes fuse during sexual reproduction.

What structure draws chromatids to opposite ends of the parent cell during mitosis?

Spindle fibers draw chromatids to opposite ends of the parent cell during mitosis.

What type of cells are eukaryotic cells?

Eukaryotic cells are those that have a nucleus or membrane enclosed cell nucleus.

What are the end products of meiosis?

The end product of meiosis is haploid cells called gametes.

What is Trisomy?

The condition in which a cell has one too many chromosomes is known as Trisomy.
