The Biology Project is fun richly illustrated and tested on 1000s of students. During this phase the chromosomes are aligned in the middle of the cell.

During mitosis all chromosomes separate into chromatids the two halves of a chromosome.

. The most basic function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells. These processes define the two major phases of the cell cycle. Due to the fact that they are fully visible at this point many scientists will study a map of an organisms chromosomes.

It has been designed for biology students at the college and high school level but is useful for medical students physicians science writers and all types of interested people. Because there are double the number of diploid chromosomes in the parent cell 2 X 2n 4n when these chromosomes are separated into. These chromatids are then separated in space before cell division to form the chromatic makeup of each daughter cell.

Each daughter cell gets one complete set of chromosomes ie one of each homologous pair of chromosomes. The only cells that undergo meiosis will become sperm or eggs. A primitive form of cell division is also found which is called amitosisThe amitotic or mitotic cell division is more atypical and diverse.

Cell division in eukaryote is much more complicated than prokaryote. In humans this means the chromosome number is reduced from 46 to 23. During this phase the chromosomes inside the cells nucleus condense and form tight structures.

In fact the chromosomes become so dense that they appear as. DNA duplication occurs during S phase S for synthesis which requires 1012 hours and occupies about half of the. Eukaryotic cell divisions can be classified as mitosis equational division and meiosis reductional division.

The joining together of a sperm and egg during fertilization returns the number of the chromosomes to 46. Depending upon chromosomal number reduced or not. The Biology Project an interactive online resource for learning biology developed at The University of Arizona.
