biology
Definition
Biology is the scientific study of life. It is a broad and diverse field that encompasses the study of all living organisms, from the smallest bacteria to the largest whales.
Biology is divided into many different subfields, each of which focuses on a specific aspect of life. Some of the major subfields of biology include:
- Cell biology: The study of cells, the basic unit of life.
- Molecular biology: The study of molecules, such as DNA and proteins, that make up living things.
- Genetics: The study of inheritance and how traits are passed from parents to offspring.
- Developmental biology: The study of how living things grow and develop from a single cell to a complex organism.
- Ecology: The study of the interactions between living things and their environment.
- Evolution: The study of how living things change over time.
- Biology is a fascinating and ever-evolving field of science. It is essential for understanding the world around us and our place in it.

AQA Science Exam Question and Answer
Question:
What is the role of DNA in biology?
Answer:
DNA is the genetic material of living things. It contains the instructions for building proteins, which are the building blocks of life. DNA is found in the nucleus of cells, and it is made up of two long strands of nucleotides.
The nucleotides in DNA are arranged in a specific order, and this order determines the instructions for building proteins. The process of converting the instructions in DNA into proteins is called gene expression.
