a By definition, bacteria do not have a true nucleus. Their DNA is not enclosed by a nuclear membrane but instead is aggregated in a central area of the cell called the nucleoid. 由定义,细菌没有一个真实的中坚力量。 他们的脱氧核糖核酸没有由一个核膜在称nucleoid的细胞的一个中心地区附寄,...

Deoxyribonucleic acid, or DNA, is the molecule that contains the genetic information in the cells of an organism. The subunits of a strand of DNA are called nucleotides.
A plasmid is a ring-shaped piece of DNA that is found within bacterial cells. Plasmids replicate independently of the chromosomal DNA found in the nucleoid but are always copied into next generation cells. Plasmids often contain genes that give bacteria genetic advantages such as antibiotic resistanc...
New generations will not arise if there is not useable organic matter in the environment, so when nutrients become extremely limited some genera of bacteria, most notably Bacillus and Clostridium, will sporulate. A fully mature spore is the most durable biological organism currently known, and ...
Prokaryotic Cells:Prokaryotic cells form unicellular organisms, unlike eukaryotic cells, which form multicellular organisms. Prokaryotes have less DNA compared to eukaryotes and contain circular DNA instead of compact chromosomes. Examples of prokaryotes include archaea and bacteria....
If the DNA within a cell is not separated from the cytoplasm, then that cell is a prokaryote. All known prokaryotes, such as bacteria and archaea, are single cells. In contrast, if the DNA is partitioned off in its own membrane-bound room called the nucleus, then that cell is a ...
