Does a cell need a nucleus to have DNA?

You don’t need a nucleus to have DNA. If you don’t have a defined nucleus, your DNA is probably floating around the cell in a region called the nucleoid.

Do all cells have a nucleus with DNA?

Aside from red blood cells and cornified cells, all other cells in the human body contain nuclear DNA. Also, all cells start with nuclear DNA. The reason for this is that DNA contains the basic code that tells each cell how to grow, function, and reproduce.

Do all cells have 1 nucleus?

Generally there is only one nucleus per cell, but there are exceptions, such as the cells of slime molds and the Siphonales group of algae. Simpler one-celled organisms (prokaryotes), like the bacteria and cyanobacteria, don’t have a nucleus.

Is it true that cells must contain DNA?

it is accepted that cells contain DNA in chromosomes and RNA in the nucleus and cytoplasm, but only in the modern cell theory. though prokaryotes (e.g. bacteria) contain DNA, they lack a nucleus. it is only in eukaryotes (e.g. animal cells) that the DNA is surrounded by a nucleus.

What cells have no nucleus?

Cells that lack a nucleus are called prokaryotic cells and we define these cells as cells that do not have membrane-bound organelles. So, basically what we’re saying is that eukaryotes have a nucleus and prokaryotes do not.

What type of cell has these characteristics contains DNA but no nucleus?

Prokaryotic cells do not have a nucleus. Instead, their DNA floats around inside the cell. Organisms with prokaryotic cells are called prokaryotes….Prokaryotic Cells.

Can cells have more than 1 nucleus?

Multinucleate cells (multinucleated or polynuclear cells) are eukaryotic cells that have more than one nucleus per cell, i.e., multiple nuclei share one common cytoplasm. For example, slime molds have a vegetative, multinucleate life stage called a plasmodium.

Do all cells have a DNA?

Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Which of the following cells do not have nucleus in it?

Prokaryotes (meaning ‘before nucleus’) are cells without a definite nucleus. The DNA floats in the cytoplasm and they divide through mitosis. RBC and platelets present in eukaryotes also do not have the nucleus.

What cells have a nucleus?

There are two basic types of cells, prokaryotic cells and eukaryotic cells. The main difference between eukaryotic and prokaryotic cells is that eukaryotic cells have a nucleus. The nucleus is where cells store their DNA, which is the genetic material. The nucleus is surrounded by a membrane.
