Organelles with their own genetic material:
1. Nucleus: The nucleus is a membrane-bound organelle found in eukaryotic cells. It contains the cell's genetic material in the form of DNA (deoxyribonucleic acid). The DNA is organized into structures called chromosomes, which consist of genes that encode the instructions for the synthesis of proteins and the regulation of cellular processes. The nucleus is responsible for controlling cell activities, including growth, metabolism, and reproduction. It acts as the control center of the cell, coordinating various cellular functions. The genetic material in the nucleus is passed on to daughter cells during cell division.

2. Mitochondria: Mitochondria are double-membraned organelles found in most eukaryotic cells. They are commonly known as the "powerhouses" of the cell due to their role in producing energy in the form of ATP (adenosine triphosphate). Mitochondria have their own circular DNA called mtDNA (mitochondrial DNA), which is separate from the nuclear DNA. mtDNA encodes a small number of genes that are involved in the production of proteins essential for mitochondrial function. These proteins are crucial for the oxidative phosphorylation process, which generates the majority of cellular ATP. Mitochondria also play a vital role in apoptosis (programmed cell death) and calcium homeostasis.

Summary:
- The nucleus and mitochondria are two organelles that contain their own genetic material.
- The nucleus houses the cell's DNA, which is organized into chromosomes and contains genes responsible for protein synthesis and cellular regulation.
- Mitochondria have their own circular DNA called mtDNA, which encodes a small number of genes involved in mitochondrial function and energy production.
- Both organelles are essential for cellular processes, with the nucleus acting as the control center of the cell and mitochondria producing ATP through oxidative phosphorylation.
