Summary Introduction

To Analyze:

The four stages that are considered to be the formation of first cells.

Introduction:

The origin of cells was the very first stage in the evolutionary theory of life on Earth. The cell is the basic structural and functional unit of any living organisms. It is the smallest unit of life which consists of cytoplasm enclosed within a membrane. This cytoplasm contains many biomolecules like proteins and nucleic acids. The cells are assumed to be evaluated in four phases:

1. The abiotic synthesis of small organic molecules like amino acids and nitrogenous bases.

2. The joining of these smaller molecules into larger polymers like proteins and nucleic acids.

3. The packaging of these molecules into protocells which are membrane enclosed droplets that separate these polymers

4. The origin of self-replicating molecules that eventually make inheritance possible.
