Anaphase
Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
Anticodon
A group of three bases on a tRNA molecule that are complementary to an mRNA codon
Apoptosis
Programmed cell death
Asters
Microtubules and fibers that radiate out from the centrioles
Centrosomes
Generates microtubules; organizes mitotic spindle
Chromatid
Each half of the chromosome
Cytokinesis
Division of the cytoplasm during cell division
Deoxyribonucleic Acid
Nucleic acid found in all living cells; carries the organism's hereditary information
Interphase
A very long part of the cell cycle; cell grows in size and chromosomes are duplicated
Metaphase
Chromosomes line up in the middle of the cell
Mitosis
The division of the cell nucleus; often followed by division of the cytoplasm of a cell
Mitotic Spindle
The structure that separates sister chromatids during mitosis
Nucleus
A dense central body in most cells containing the genetic material of the cell
Prophase
Chromosomes become visible, nuclear envelope dissolves, spindle forms
Ribonucleic Acid
The nucleic acid that contains ribose; acts in protein synthesis
Ribosomal RNA (rRNA)
The RNA component of the ribosome, and is essential for protein synthesis
Telophase
Final phase of mitosis during which new cells prepare for their own independent existence
Transcription
The process of making a copy of genetic information stored in a DNA strand into a complementary strand of RNA (messenger RNA or mRNA) with the aid of RNA polymerases.
Transfer RNA (tRNA)
Transfers appropriate amino acids to the ribosome for building the protein
Translation
The process of making proteins using the transcribed mRNA and ribosomes.
Triplet Code
3 bases of DNA that code for a single amino acid
