Question | Answer |
DNA | a chemical that contains information for an organism's growth and functions |
chromosomes | a structure in the nucleus of a cell, made of DNA,and containd the genetic information |
chromatids | one of two identical chromosomal strands into which chromosome splits up-and-down |
cell cycle | the normal sequence of development and division of a cell |
mitosis | the part of the cell cycle during which the nycleus divivdes |
interphase | the period in the cell cycle where the cell lives most of its life growing, developing, and getting prepared for seperation |
double helix | the spiral arrangement of the two complementary strands of DNA. |
cytokinesis | division of the cytoplasm of a cell, occurring at the end of mitosis |
centromere | holds together 2 chromatids in an X shape |
binary fission | fission into two organisms approximately equal in size. |
regeneration | the restoration or new growth by an organism of organs, tissues, etc., that have been lost, removed, or injured. |
asexual reproduction | reproduction only using one cell/organism |
sexual reproduction | reproduction using 2 cells/organisms |
prophase | first stage of mitosis during which the nuclear envelope breaks down and strands of chromatin form into chromosomes. |
metaphase | second stage in mitosis in which the duplicated chromosomes line up along the equatorial plate of the spindle. |
anaphase | third stage in mitosis in which the daughter chromosomes move away from each other to opposite ends of the cell. |
telephase | the final stage of mitosis, in which the separated chromosomes reach the opposite poles of the dividing cell and the nuclei of the daughter cells form around the two sets of chromosomes. |
centrioles | a small, cylindrical cell organelle, seen near the nucleus in the cytoplasm of most eukaryotic cells, that divides in perpendicular fashion during mitosis, |
budding | a process of asexual reproduction in which an organism develops as an outgrowth of the parent. Then it breaks free once grown all the way and becomes sperate and independent |
