What is the important function of cytoplasm? The cytoplasm is responsible for holding the components of the cell and protects them from damage. It stores the molecules required for cellular processes and is also responsible for giving the cell its shape.

In cell biology, the cytoplasm is a highly viscous (gel-like) substance enclosed within the cell membrane. It’s composed of water (about 85 percent), proteins (10 to 15 percent), lipids (2 to 4 percent), nucleic acids, inorganic salts and polysaccharides in smaller amounts.
Does cytoplasm have DNA?
All of the genetic information in a cell was initially thought to be confined to the DNA in the chromosomes of the cell nucleus. It is now known that small circular chromosomes, called extranuclear, or cytoplasmic, DNA, are located in two types of organelles found in the cytoplasm of the cell.
Is an extrachromosomal DNA?
Extrachromosomal DNA (eDNA) is mammalian cells is represented not only as mitochondrial DNA but also as circular DNA existing both in the nucleus and in the cytoplasm. According to its size eDNA could be divided into two major classes: small polydisperse circular DNAs and large circular DNAs.
Where are DNA found?
Does the human body have RNA?
RNA has been found in a panoply of human body fluids: blood, urine, tears, cerebrospinal fluid, breast milk, amniotic fluid, seminal fluid and others.
