What are cancer cells?

Cancer cells are our own cells that have had their DNA (instructions/code) damaged, so that when they replace themselves, the new cells have lost their function.  They have become "mutations" with no purpose and grow uncontrolled.  If they grow into, or interfere with, other organs they are called malignant.

How are cancer cells formed?

Some answers are really big and some are inaccurate.I will try to explain in the simplest language-You have trillions of cells in your body.Sometimes you get a cell which is bad or unhealthy. It has a mutation in its DNA.This cell is unwanted and your body gets

Is cancer caused when cells stop multiplyng?

Exactly.When cells stop dying, they are called as tumors. When the undying cells start invading into nearby organs (which benign tumors won't do), then they are called as cancer cells.Karthick Mani's answer to What are the mechanisms by which cancer patients die from cancer?

Can viruses be said as cell organelles?

Thanks for A2A,No, viruses cannot be called as a cell organelle.A cell organelle is defined as a part of the cell which is membrane-bounded and carries out some basic metabolic process inside the cell (except Ribosome, which is not a membrane-bounded organelle). Viruses are not a cell organelle, instead, they are just the assembly of proteins,

Do viruses have a cell wall?

No, viruses are acellular, therefore they do not have cell wall. The body of viruses are made up of proteins and nucleic acid (either DNA or RNA) only.

Is it better for a battery to have more cells or fewer large cells?

Whoever answers this question should be an Electrical Engineer with a degree as well as having years of experience in the battery industry. Everyone else including myself will be giving an opinion which is not what the OP wants or needs.I think every battery application requires design tradeoffs as

How do cancer cells attack normal cells?

Hi,Cancer cells as such donot attack normal cells directly, but cancer cells have some specific features which makes their survival better than other cells.Any normal cell, when gets damaged or suffers loss of function, it either undergoes apoptosis(self death) or phagocytosed by immune cells of body. Cancer cells evade immune system and

How long can one survive without any proteins?

You would die very, very quickly, if not instantly. Without proteins, these would be some of the immediate effects:Proteins make up ~50% of the dry mass of a cell, so you'd lose a great deal of your body mass in an instant.Without actin, myosin and tubulin, each of your cells would

Do viruses and fungi have cells?

Viruses are not composed of cells. A complete virus particle (virion) is a complex of nucleic acid surrounded by proteins. They are much smaller than a cell (diameter about 20–300 nm, although a few considerably larger forms are known too), and they are not considered as living organisms

Can an organism survive without DNA?

Well, apart from RNA-viruses that have been mentioned already, there are conjectures that DNA is of viral origin (Page on www.college-de-france.fr). Namely, DNA viruses gradually replaced functional RNA genomes that evolved out of the RNA world.Whether or not these conjectures

Can L. acidophilus survive in the human stomach?

Yes, it can live, but it cannot thrive. The population will decline about tenfold within an hour in the stomach.The optimal pH for growth seems to be about 6.0 to 6.5, according to the literature. Particular details may vary by strain.

Can we live without bacteria?

The short answer is: No. The long answer is not really, though it has been tried. In order to test whether bacteria were essential, newborn mice were carefully raised in a completely sterile environment, fed sterilized food, and allowed

What causes cancer cells to die?

Anything which will cause apoptosis. There are many ingedients for this recipe. Ie: Oxygen, Hydrogen peroxide( See Dr. Otto Warburg) and according to standard medical protocol, chemotherapy which does not create apoptosis,but rather kills the cell directly by way of it's toxcity. Keep in mind that the chemotherapy kills healthy cells as well.

Can viruses be said as cell organelles?

Hahaha... u think so..? Unfortunately u r wrong..How a living organism can be a cell organelle ? Did u find a virus everytime u cut a section of cell... Noso clearly Viruses are far different from cell organelles... An organelle (think of it

What is the substance in sugar that causes our body's cells to rot?

It is a surplus of sugar itself, which is oxidized by the liver that leads to free radical damage of our arteries and cells. The devil is in the details, which I am explaining below. You will learn how sugar really

Do viruses have a cell wall?

According to virology, viruses are pseudo-living acellular organism. The virions (i.e.; viral particles) consist of nucleic acids (DNA or RNA), that carry genetic information, protected by a protein coat. This protein coat is known as capsid. Some viruses envelope themselves in a modified form of one of the cell membranes but these cell membranes are derived

What happens if a cell dies in the human body?

It would depend on many things. Was the body not refrigerated because it was not found soon enough? Was there a Crime committed?Did the person live alone, and didn't have anyone who checked in on them regularly? It doesn't take long after

Million of our cells dying every seconds Nothing to worry about it . You are better off without them .There are two kind cell death1.Apoptosis ( Planned )2.Necrosis ( Unplanned )In Apoptosis type.Each cells equipped with the instructions and instruments necessary for their own self-destruction.They keep these tools carefully hidden,until

What are the main features of an animal cell?

Animal cells have many distinct characteristics when compared to plant cells, including their varied shapes, their many types of organelles, their centrioles, cilia and lysosomes, and their cell-to-cell junctions. Animal cells also lack chloroplasts and cell walls, which are found in plant cells.The varying and irregular shapes of animal cells are a distinct characteristic, while plant cells have

Thank you for the A2A. Um, let's deal with this simplistically.First of all, cell division of sexually reproductive cells, known as gametes, experience meiosis. So, a sperm cell, for SRY active XY individuals, that divides experiences meiosis. An ovum, or an egg, for

What two structures are found in a plant not animal cells?

The cell wall, chloroplasts and vacuole are found in plant cell rather than animal cells. These components are know as organelles of a cell and these organelles for a plant are vital for its functionality and survival. Although Animal cells may have many small vacuoles, but mostly it is absent..
