The three organelles that contain DNA are the nucleus, mitochondria and chloroplasts. Organelles are membrane-bound subunits within a cell — analogous to organs in the body — that perform specific functions. The nucleus is the control center of the cell, and houses genetic information.
which organelles contain their own genetic material?
The two cell organelles which contain their own genetic material are namely: Mitochondria (present in all eukaryotic cell) and chloroplast (present in organisms belonging to Plant Kingdom only).
what is genetic material composed of?Genetic material is called DNA and RNA. DNA is the hereditary material found in the nucleus of eukaryotic cells (animal and plant) and the cytoplasm of prokaryotic cells (bacteria) that determines the composition of the organism.
which organelles does not contain DNA?
So if we are speaking of cell organelles that do not contain DNA, then the correct answer is ER (Endoplasmic Reticulum). Answer: Lysosomes and Vacuoles do not contain DNA. Lysosomes are bounded membrane organelles which are found in the cells of animals and plants.
Which organelle other than the nucleus contains genetic material?
The organelle other than ‘nucleus‘ containing the DNA is the c) mitochondria. In addition to the chromosomal DNA the mitochondria contains nucleic material which is called as the mitochondrial DNA. This ‘mitochondrial DNA‘ is conserved for generations without destruction.
What two organelles contain their own DNA?
Mitochondria and chloroplasts are the only two organelles of animal and plant cells that contain their own DNA.
Which organelle has its own DNA?
Can you name the two organelles?
1. Can you name the two organelles? Answer: The cell organelles plastids and mitochondria have their own genetic material.
What are the two organelles?
Different Organelles and their Functions Plasma Membrane. Nucleus/DNA. Ribosome. Mitochondria. Vacuoles. Cytoskeleton. Plastids. Endoplasmic Reticulum.
Does plastids have their own genetic material?
Both, mitochondria and plastid possess their own genetic material and ribosomes and thus, the are called as semi-autonomous organelles. The mitochondrial DNA and plastid DNA possess genes which produce the proteins necessary for the functioning of mitochondria and plastids respectively.
Where is protein synthesis in a cell?
Ribosomes are the sites in a cell in which protein synthesis takes place. Cells have many ribosomes, and the exact number depends on how active a particular cell is in synthesizing proteins. For example, rapidly growing cells usually have a large number of ribosomes (Figure 5).
What is the only organelle that prokaryotes have?
Prokaryotes lack an organized nucleus and other membrane-bound organelles. Prokaryotic DNA is found in a central part of the cell called the nucleoid. The cell wall of a prokaryote acts as an extra layer of protection, helps maintain cell shape, and prevents dehydration.
Is DNA an organelle?
DNA is a very long molecule made up of nucleotide molecule sub units. DNA is a macromolecule, it is not an organelle. In eukaryotic (nucleated) cells DNA is contained within an organelle called the nucleus.
Does the Golgi apparatus have DNA?
Golgi Apparatus are involved in Intracellular Protein Modification and Vesicular Trafficking… They don’t contain any genetic material such as DNA or RNA. In case of Animal Cells, only Nucleus and Mitochondria Contain DNA.
