Question/term | Answer/definition |
---|---|
cytokinesis | Complete separation of the 2 new cells resulting from mitosis. |
mitosis | A process that takes place in the nucleus of a dividing cell, involves a series of steps, and results in the formation of two new nuclei each having the same number of chromosomes as the parent nucleus. |
interphase | Period of time where a cell carries out cell processes and replicates DNA prior to cell division |
prophase | Chromatin condenses into chromosomes |
metaphase | Chromosomes line up in the middle of the cell |
anaphase | Sister chromatids separate |
telophase | After the chromosome separates, the cell seals off, Final Phase of Mitosis. |
chromatid | Each half of the chromosome |
chromosome | A doubled rod of condensed chromatin; contains DNA that carries genetic information |
centromere | Area where the chromatids of a chromosome are attached |
cell cycle | An ordered sequence of events ; process of growth and division. |
Centriole | organelle the sends out spindle fibers |
Spindle fiber | emerge from centrioles, attach to chromosomes to pull them apart during mitosis |
Purpose of mitosis | divides cells that are too large, replaces damaged/dying cells, allows for growth |
7 | If a parent cell has 7 chromosomes, and it goes through mitosis, how many chromosomes will each daughter cell have? |
14 | If there are 7 duplicated (replicated) chromosomes? How many chromatids are there? |
sister chromatids | identical copies of DNA joined together at a centromere to form a duplicated chromosome |
23 | how many pairs of chromosomes in a human cell? |
46 | Diploid Chromosome Number in Humans |
23 | Haploid Chromosome Number in Humans |
DNA | Deoxyribonucleic acid containing the genetic information that makes up the chromosomes. |
nucleus of a cell | Where is DNA found? |
CAGGTA | If one strand of a DNA double helix has the sequence GTCCAT, what is the sequence of the other strand? |
