Do bacteria have both RNA and DNA?

Bacteria have both RNA and DNA. The bacteria’s genomic chromosome is composed of DNA, as are any extrachromosomal plasmids. The RNAs may be…

Does all bacteria have DNA?

What are the basic properties of the genomes of bacteria? Most bacteria have a genome that consists of a single DNA molecule (i.e., one chromosome) that is several million base pairs in size and is “circular” (doesn’t have ends like chromosomes of eukaryotic organisms).

Do viruses have RNA or DNA?

​Virus. A virus is a small collection of genetic code, either DNA or RNA, surrounded by a protein coat. A virus cannot replicate alone. Viruses must infect cells and use components of the host cell to make copies of themselves.

Is DNA present in bacteria?

The genetic material of bacteria and plasmids is DNA. Bacterial viruses (bacteriophages or phages) have DNA or RNA as genetic material. The two essential functions of genetic material are replication and expression.

Do prokaryotes have RNA or DNA?

The distinction is that eukaryotic cells have a “true” nucleus containing their DNA, whereas prokaryotic cells do not have a nucleus. Both eukaryotes and prokaryotes contain large RNA/protein structures called ribosomes, which produce protein, but the ribosomes of prokaryotes are smaller than those of eukaryotes.

What do you call a virus that attacks bacteria?

Bacteriophage: ↑ A virus that infects bacteria, also called a phage.

Where is the DNA of a bacteria?

nucleoid
The DNA of most bacteria is contained in a single circular molecule, called the bacterial chromosome. The chromosome, along with several proteins and RNA molecules, forms an irregularly shaped structure called the nucleoid. This sits in the cytoplasm of the bacterial cell.

Do bacteria cells have DNA?

The DNA of most bacteria is contained in a single circular molecule, called the bacterial chromosome. This sits in the cytoplasm of the bacterial cell. In addition to the chromosome, bacteria often contain plasmids – small circular DNA molecules.
