Multicopy genomes are also common among bacteria. For example, the cells of E. coli growing rapidly in a rich medium (20-min doubling time) at low cell density are large and contain about ten genome equivalents of DNA per cell, whereas the number is between one and two in small cells ...
- Statement: "Bacteria have small circular DNA." - Evaluation: This statement is correct. Bacteria typically possess a single, circular strand of DNA, which is distinct from the linear DNA found in eukaryotic cells. 5. Analyzing Statement 4: - Statement: "Pili help in the attachment and th...

The role of messenger RNA (mRNA) in biological systems is extremely versatile. However, it’s extremely short half-life poses a fundamental restriction on its application. Moreover, the translation efficiency of mRNA is also limited. On the contrary, circular RNAs, also known as circRNAs, are ...
Plasmids are extra-chromosomal small circular DNAs that are capable of replicating independently of the host, and are present throughout a variety of different microorganisms, most notably bacteria. While plasmids are not essential components of the host, they can impart an assortment of survival ...

Extrachromosomal circular DNA (eccDNA) is considered a circular DNA molecule that exists widely in nature and is independent of conventional chromosomes. eccDNA can be divided into small polydispersed circular DNA (spcDNA), telomeric circles (t-circles), microDNA, and extrachromosomal DNA (ecDNA) ...
