During interphase, there are three stages. During the __________ phase, the cell grows. During the ___________ phase, the genetic material (DNA) of the cell is copied. During the ____________ phase, the cell prepares for division. The events that make up the life of a cell are called the _________________. The two main parts of this cycle are ___________________ and ___________________. Each chromosome has two identical sections of DNA called ______________ that are connected at a region called the _____________________. These identical sections of DNA must separate during cell division. Uncoiled DNA and proteins are called ____________________, which coils up during cell division to form ____________________. In eukaryotic cells, cell division is a little more complicated. In these cells, DNA is found in the ____________. During prokaryotic cell division, DNA is copied and divided into two identical ____________ cells. This process is called ______________________. Another reason cells cannot grow forever is that the _______________ of their membrane does not increase as quickly as the ________________, which limits the necessary transport of materials into and out of the cell. To make large organisms (ex: plants and animals), cells divide because they can’t continue to grow forever. One reason they can’t grow forever is they will not have enough __________ to control a massive cell’s activities. daughter DNA interphase volume binary fission G1 nucleus cell cycle chromatin chromatids centromere S chromosomes cell division G2 prophase mitotic spindle cleavage furrow metaphase mitosis nuclear membrane anaphase centromere cytokinesis telophase centrioles cell plate surface area After mitosis, the cytoplasm divides in a process called cytokinesis. In animal cells, the cell membrane pinches in to form a __________________. In plant cells, a _________________ forms between the two new daughter cells. During ____________________, two nuclear membranes reform, chromosomes uncoil, and the mitotic spindle breaks down. At this point, nuclear division is complete. During ___________________, spindle fibers pull apart chromatids and carry new daughter chromosomes to opposite ends of the dividing cell. During ___________________, spindle fibers arrange chromosomes at the center of the cell along a line called the metaphase plate. Spindle fibers attach to chromosomes at the ___________________. In this stage, the ________________________ also begins to form when proteins called microtubules grow from structures at either end of the cell called _______________________. During _________________, the _____________________ breaks down and chromatin coils into chromosomes. Cell division involves two parts, mitosis and cytokinesis. _______________ is division of the nucleus, and _______________ is division of the cytoplasm.
