Question

A bacterial genome refers to the total number of genes located on
A. Single chromosome
B. Haploid set of chromosome
C. Diploid set of chromosome
D. Tetraploid set of chromosome

Answer 1

Hint: The genome consists of all the chromosomes and the carrying genes. These are variable. The bacteria have evolved over time to be free living. These have the tendency to evolve depending on the host.

Complete answer: A genome is an organism's complete DNA including the genes. It contains the basic information to build the characters and genetic material of an organism. Bacterial genome comprises chromosomes and all the genetic material. These are variable and have a diversity in all the organisms. These are smaller and less variant in size.
Bacteria have a compact genome as compared to eukaryotes. The genes in bacteria are structured into operons. These possess a non coding DNA in the form of introns. The study was given by Cole et al. He discovered Mycobacterium leprae with increased no of pseudogenes. Over the time the bacterias have led to free living. These can be further pathogens or symbionts. These play a major role in bacteria size and functionality.
On transition from free living to facultative they lose genes making them host dependent.
Bacteria have a single chromosome as a DNA. It is a circular molecule of the DNA as its genetic material. They have a single set of chromosomes. In case of eukaryotes there is a diploid chromosome.

The correct answer is A i.e single chromosome.

Note: The bacterial genome is on a single chromosome. In case of eukaryotes there is a diploid set of chromosomes. These carry the basic genetic information with the genes.
