Where is DNA made in prokaryotes?
Where is DNA made in prokaryotes?
the nucleoid
In prokaryotic cells, the DNA is mostly located in a central part of the cell called the nucleoid, which is not enclosed in a nuclear membrane. Most of the genetic material in most prokaryotes takes the form of a single circular DNA molecule, or chromosome.
Where is DNA made Where are proteins made?
The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm. Translation, the second step in getting from a gene to a protein, takes place in the cytoplasm.
Where is DNA located in prokaryotic and eukaryotic cells?
Eukaryotic chromosomes are located within the nucleus, whereas prokaryotic chromosomes are located in the nucleoid.
How are proteins made in DNA?
Proteins are the key working molecules and building blocks in all cells. They are produced in a similar two-step process in all organisms called protein synthesis – DNA is first transcribed into RNA, then RNA is translated into protein.
How is DNA used to make a protein?
First, enzymes read the information in a DNA molecule and transcribe it into an intermediary molecule called messenger ribonucleic acid, or mRNA. Next, the information contained in the mRNA molecule is translated into the “language” of amino acids, which are the building blocks of proteins.
How is prokaryotic DNA different from eukaryotic?
The structure and chemical composition of the DNA in both the eukaryotic and prokaryotic cells are different. The prokaryotic cells have no nucleus, no organelles and a very small amount of DNA. On the other hand, the eukaryotic cells have nucleus and cell organelles, and the amount of DNA present is large.
Where is the DNA in a prokaryote in a eukaryote?
1: Cellular location of eukaryotic and prokaryotic DNA: Eukaryotic DNA is stored in a nucleus, whereas prokaryotic DNA is in the cytoplasm in the form of a nucleoid.
Where is the DNA in prokaryotes and eukaryotes?
How is DNA organized in prokaryotic cells?
Genetic information in prokaryotic cells is carried on a single circular piece of DNA which is attached to the cell membrane and in direct contact with the cytoplasm. There is no enclosing membrane, so there is no true nucleus, but simply a concentration of DNA known as a nucleoid.
