Replication of DNA occurs in the "S" phase (or Synthesis phase) of the cell cycle process. Usually, people perform cell cycle analysis on cells fixed at progressively differing time points. In our laboratory, we fix our cells with 70% EtOH at 0, 12, 18, 24, and 48 hours. Then we use a FACS calibur machine to visualize and quantify the percentage of cells in each phase of the cell cycle.

animal cell\ncell membrane - controls what moves in and out of the cell\ncytoplasm - the jelly like substance the organelles sit in\nnucleus - controls the actions of the cell\nlysosome - structure with digestive enzymes that break down wornout cells and debris\nvacuole - stores food, water, and wastes\nnuclear membrane/envelope - controls what moves in and out of the nucleus\nribosomes - synthesize and produce proteins\nendoplasmic reticulum - synthesizes materials and transports them to other parts of the cell\ngolgi body - packages and modifies materials and sends them to other cells\nchromatin - genetic information that tells the what to do\nnucleolus - knot of chromatin that produces ribosomes\nmitochondria - produces energy for cell\n\nPlant cell ( added on )\ncell wall - a rigid layer that gives shape and supports the cell\nchloroplasts - absorbs sunlight needed for photosynthesis

chemical, cellular, tissue, organ, organ system, organism\n\nchemical - stuff that comprises a cell and the processes within\ncellular - smallest unit of sustained life\ntissue - group of cells working together\norgan - a lot of tissue\norgan system - several organs that work together\norganism - a person could be considered an organism.

Depends on the cell type labile, stable, non regenerative etc

mitosis is the normal mode of cell multiplication and increasing there number without a change in their constiution so it occurs in all the SOMATIC CELLS (normal cells of body not involved in sexual reproduction).\nmeiosis occur in gamete forming cells as it is the reductoinal division

There are many different kinds of cells. Eukaryotic (mostly all animal, fungi, and plant cells), Prokaryotic (bacteria), and then there are specialized cells in most organisms. I.E. storage cells, bacteria-fighting cells, hormone producing and recieving cells. I am not sure that there is a set number of different kinds. However, the Prokaryotic and Eukaryotic division is the beginning of differentiation among all cells. It is used to help differentiate different kingdoms of organisms.

Cell culture is the process by which either prokaryotic or eukaryotic cells are grown under controlled conditions. In practice the term "cell culture" has come to refer to the culturing of cells derived from multicellular eukaryotes, especially animal cells. The historical development and methods of cell culture are closely interrelated to those of tissue culture and organ culture.\n\nAnimal cell culture became a routine laboratory technique in the 1950s,[1] but the concept of maintaining live cell lines separated from their original tissue source was discovered in the 19th century.[2]\n\nYou could get more information from the link below...

The nucleus contains the cell's genetic material and control's the cell's activities.

Mitosis result in 2 cells that are typical to the parent cell. it also occurs in all type of cells\nMeiosis result in 4 cells each of them have half of the chromosomal material of the parent cell. it occurs in gametes

The first thing you will see is the structure of the cells which form tissue. Inside the cell, there's nuclues which contols all the activities in the cell. Protoplasm stands for cytoplasm and nuclues(extra info).

Cell bio would encompass all things on a cellular level.\nUsually organisms with a "life of their own".\nMolecular bio goes further into the atomic level.\nEg: a molecule of water (H2O) consists of 3 atoms. take a H away and you have Hydrogen peroxide(HO). A cell is usually made up of many different molecules when added together, make an organism like a liver cell, cancer cell, stem cell,etc...

Certain genes are turned on in various cells, the different genes taht are activated lead cells to differentiate

mitochondria is in the cell and is used for anerobic respiration. the cell uses mitochondria for energy (ATP)

1)  The cell is the unit of structure, physiology, and organization in living things. \n   2)  The cell retains a dual existence as a distinct entity and a building block in the   construction of organisms. \n   3)  Cells form by free-cell formation, similar to the formation of crystals (spontaneous generation).\n\nKeep this as hint and do your homework

each organ performs a specific function for the organism, just like organelles perform a specific function for the cell.  hence organelle, "little organ."
