Where is DNA found in a eukaryotes cell?
nucleus
What bacteria is circular double-stranded DNA molecule that is capable of independent replication?
The bacteria that meets this description is a plasmid. Plasmids are small, circular pieces of DNA that replicate independently from the bacterial chromosome. They can carry additional genetic information and can be transferred between bacterial cells.
Is the bacterial chromosome found in the nucleus?
Bacteria are prokaryotic that is they lack a nucleus,hence there DNA is not present in nucleus but in nucleoid which is also celled chromatin body.Actually DNA is in form of a large double stranded circular double helical molecule of DNA also called bacterial chromosome .In addition to chromosomes, small DNA molecules are also present in Bacteria called Plasmid .
What are the genetic differences between bacteria cells and human body cells?
One key genetic difference is the presence of a nucleus in human cells, which bacteria lack. Human cells have linear chromosomes enclosed within the nucleus, while bacteria have a single circular chromosome located in the cytoplasm. Additionally, bacteria may have plasmids, small circular DNA molecules that are often absent in human cells.
Circular DNA molecule that is not part of the chromosome in bacterial cells?
The circular DNA molecule that is not part of the bacterial chromosome is called a plasmid. Plasmids are small, extrachromosomal pieces of DNA that can replicate independently of the bacterial chromosome. They often carry genes that provide bacteria with additional functions, such as antibiotic resistance.
Is there at least one species of bacteria that has a nucleus?
No, there is no bacterium that has a nucleus.A nucleus is defined by the membrane that surrounds it. In prokaryotic cells such as bacteria, there are no internal membranes. So there is no nuclear membrane, and no nucleus.The genome (genetic information) is dispersed among one circular DNA molecule (the chromosome) and a number of small rings of DNA called plasmids.The region of the cell in which the chromosome lies is called the nucleoid.
How many chromosomes does a bacterium have?
Bacteria do not have chromosomes. They have a small circular piece of DNA within the cell. The chromosome of a bacterium is the single molecule of circular DNA. It is also called as nucleoid.
Can DNA be found in bacterial cells?
Yes, DNA is present in bacterial cells. Bacterial DNA is typically found in a single circular chromosome located in the nucleoid region of the cell. Some bacteria may also contain plasmids, which are small circular DNA molecules that can replicate independently of the main chromosome.
Is a circular double stranded DNA molecule that is capable of independent replication it usually occurs in bacteria?
Yes, this description matches that of a bacterial plasmid. Plasmids are small, circular DNA molecules that replicate independently of the bacterial chromosome. They often carry accessory genes that can provide advantages to the bacteria under certain conditions.
Is plasmid located in the nucleus or cytoplasm?
No they are not in the nucleus. They are in the cytoplasm.
What is nucleus of bacterial cell?
Bacterial cells do not have a true nucleus like eukaryotic cells. Instead, they contain a nucleoid, which is an irregularly shaped region in the cytoplasm where the bacterial chromosome, a single circular DNA molecule, is located. The nucleoid is not surrounded by a membrane, allowing for direct interaction with the cytoplasmic components involved in processes like transcription and translation. Additionally, bacteria may contain plasmids, which are small, circular pieces of DNA that can carry additional genetic information.
Where in a cell is a bacterium's genetic material?
In a bacterium, the genetic material is located in the nucleoid, which is an irregularly shaped region within the cytoplasm. Unlike eukaryotic cells, bacteria do not have a membrane-bound nucleus; instead, their DNA is typically a single circular chromosome that is not enclosed in a membrane. Additionally, bacteria may contain plasmids, which are small, circular DNA molecules that can carry extra genetic information.
