What part of the cell contains its own DNA and ribosomes?
Mitochondria are oval-shaped, double membrane organelles that have their own ribosomes and DNA. These organelles are often called the “energy factories” of a cell because they are responsible for making adenosine triphosphate (ATP), the cell’s main energy-carrying molecule, by conducting cellular respiration.
What produces ribosomes and ribosomal DNA?
The nucleolus is a region found within the cell nucleus that is concerned with producing and assembling the cell’s ribosomes.
Do bacteria have DNA and ribosomes?
Prokaryotic Cell. This diagram shows the structure of a typical prokaryotic cell, a bacterium. Like other prokaryotic cells, this bacterial cell lacks a nucleus but has other cell parts, including a plasma membrane, cytoplasm, ribosomes, and DNA.
Do all cells contain ribosomes and DNA?
All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. The plasma membrane, or cell membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment. Ribosomes are the non-membrane bound organelles where proteins are made, a process called protein synthesis.
What cell part contains ribosomes?
Ribosomes are found ‘free’ in the cell cytoplasm and also attached to rough endoplasmic reticulum. Ribosomes receive information from the cell nucleus and construction materials from the cytoplasm.
What do ribosomes produce?
Ribosomes facilitate the synthesis of proteins in cells (i.e., translation) (see Figs. 1-1 and 1-3). Their function is to “translate” information encoded in mRNA into polypeptide chains of amino acids that make up proteins.
Why mitochondria have their own DNA and ribosomes?
Mitochondria have their own DNA, which is separate from the DNA found in the nucleus of the cell. And both organelles use their DNA to produce many proteins and enzymes required for their function.
Which is cell contains its own DNA and ribosomes?
Both the mitochondria and chloroplast organelles of a plant cell carry their own DNA and ribosomes. Click to see full answer. Considering this, what contains its own DNA and ribosomes? Both mitochondria and chloroplasts contain their own DNA and ribosomes.
What are the organelles that have their own DNA?
[SOLVED] The cell organelles having their own DNA and ribosomes are:A. Endoplasmic Reticulum and LysosomesB. Mitochondria and plastidsC. Golgi Apparatus and PlastidsD.
Where is the DNA stored in a plant cell?
Normally, the DNA of a cell is stored in the nucleus of the cell. However, there have been discoveries of two other organelles within a plant cell that may contain both DNA and ribosomes, the protein making machines. Become a Study.com member to unlock this answer!
Where is most of the DNA found in a cell?
Nearly every cell in a person’s body has the same DNA. Most DNA is locatedin the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
