There are types of cells prokaryotic and eukaryotic. In order to understand DNA, it is necessary to understand the cell. So read it till the end and like our Facebook page for regular updates.
There are two types of cells:
(1) eukaryotic cells and
(2) prokaryotic cells.
Prokaryotic cells
A cell which does not have a nucleus is called a prokaryotic cell. Generally it is a unicellular organism, such cells include bacteria and archaea
Prokaryotic cells
Prokaryotic cells were the first form of life on Earth, carrying out important biological processes, including cell signaling.
Prokaryotic cells
The DNA of a prokaryotic cell consists of a single circular chromosome, which is in direct contact with the cytoplasm.
Prokaryotic cells
That is to say, a prokaryotic cell may not have a nucleus, but it does have a nucleoid region, and it contains genetic material.
Eukaryotic Cells
Under this, those cells are kept, which have a nucleus. It can be unicellular as well as multicellular. Plants, animals, fungi, protozoa, and algae are all eukaryotic.
Eukaryotic Cells
Eukaryotic DNA is organized into one or more linear molecules, called chromosomes, which are linked by histone proteins.
Eukaryotic Cells
All chromosomal DNA is stored in the nucleus of the cell, separated from the cytoplasm by a membrane
Eukaryotic Cells
The main feature of eukaryotes compared to prokaryotes is its compartmentalization: that is, the closed parts of the cell that are usually surrounded by a single or double lipid layer membrane
