DNA Structure

 The DNA is  deoxyribonucleic acid that is small molecule in cell and located and mixed with chromosome found in nucleus . It is double helix structure and stored as  code for genetic information. The DNA can be used as a code to analyze and identify the bodies , test disease and genetic information. 

The video and image below show the DNA Structure. 

  

Cell nucleus

 It is the smallest organelle in cell and surrounded by membrane called nucleus membrane. It contains chromosome that is complicated structure and own DNA. This organelle is the basic and major thing in the structure of cell because it saves the genetic information.

Structure of Cell in Animal

The structure of cell consist of  several organelles that is complicated in their function, communication with each other chemically and physically. The organelles are cell membrane, cytoplasm, nucleus, golgi body etc.

What is the cell biology?

The cell biology is the field of study that describes the cells in different elements such as its structure, content, biological functions, and interacting with other cells. Cell biology plays in different areas such as genetics, immunology etc.

The video below shows more information about the field of cell biology and its definition.
