Bacterial chromosome isa)single stranded and circularb)double stranded...
Bacterial chromosome is double stranded and circular.
Explanation:
- Bacteria are prokaryotic organisms, which means they lack a true nucleus and membrane-bound organelles.
- Instead of a nucleus, bacterial DNA is organized into a single, circular chromosome located in the cytoplasm.
- This chromosome is double stranded, meaning that it consists of two complementary strands of DNA running in opposite directions and held together by hydrogen bonds between their nitrogenous bases.
- The circular shape of the bacterial chromosome allows for efficient replication and segregation during cell division.
- In addition to the main chromosome, some bacteria also carry plasmids, which are smaller, circular pieces of DNA that can replicate independently of the main chromosome and often carry genes that confer advantages such as antibiotic resistance or the ability to produce toxins.
