Cellular and Sexual Reproduction

First stage of mitosis, during which the cell's chromatin condenses into chromosomes.

• Prophase

• Metaphase

• Anaphase

• Telophase

NGSS.HS-LS1-4

Programmed cell death

• Cyclin

• Cyclin-dependent kinase

• Apoptosis

• Cytokinesis

Cell division in which the sister chromatids do not separate correctly, resulting in gametes with an abnormal number of chromosomes.

• Cellular Differentiation

• Nondisjunction

• Crossing Over

• Telomere

NGSS.HS-LS3-2

Unspecialized cell that can develop into a specialized cell under the right conditions.

• Haploid

• Diploid

• Allele

• Stem Cell

Tags

NGSS.HS-LS1-4

Last stage of mitosis in which nucleoli reappear. Two new nuclear membranes begin to form, but the cell has not yet completely divided.

• Prophase

• Metaphase

• Anaphase

• Telophase

NGSS.HS-LS1-4

Cancer-causing substance.

• Stem Cell

• Carcinogen

• Cyclin-dependent kinase

• Cyclin

Tags

NGSS.HS-LS3-2

Chromosome that is not a sex chromosome.

• Autosome

• Gamete

• Allele

• Telomere

Second stage of mitosis in which motor proteins pull sister chromatids to the cells equator.

• Prophase

• Metaphase

• Anaphase

• Telophase

NGSS.HS-LS1-4

One of the specific proteins that regulate the cell cycle.

• Nucleosome

• Chromatin

• Cyclin-dependent kinase

• Cyclin

Exchange of chromosomal segments between a pair of homologous chromosomes during prophase I of meiosis.

• Crossing Over

• Karyotype

• Fertilization

• Autosome
