Cell division (1) -Prokaryotes divide by __ . By contrast, in eukaryotes the cell division occurs in two stages: __ (nuclear division) and __ (cytoplasmic division). -The __ information is contained in __ made up of DNA and proteins. After the DNA replication each chromosome consists of two identical __ attached at an area called __ -The number of chromosomes varies from one species to another. Almost all human cells contain __ chromosomes.Only gametes contain __ chromosomes. -During the cell cycle , a cell grows, prepares for division (during the __ ), and divides to form two daughter cells (during the __ ), each of which then begins the cycle again. -The cell cycle can be divided into different stages: M phase ( __ and __ ) and Interphase ( __ __ , and __ phases).
