Non-Mendelian Inheritance: Maternal Mitochondrial Genes

What are the unique features of mitochondria that are not present in other cellular organelles in human cells?

Summary Introduction

To explain: The unique features of the mitochondria that are absent from other cellular organelles of human cells.

Introduction: Cytoplasmic organelle, mitochondria, synthesize the energy-rich ATPs (Adenosine Triphosphate) to provide energy to the body. ATP is used in various metabolic processes of the body. That is why mitochondria are also called the powerhouse of the cell.

Explanation of Solution

The unique features that make mitochondria different from other organelles are described as follows:

  • • According to symbiotic theory, it is believed that mitochondria were evolved from the free-living bacteria that get adapted to live inside the human cells. Other cellular organelles do not show this kind of evolution.
