Detailed explanation-1: -The genetic material of bacteria and plasmids is DNA.

Detailed explanation-2: -Bacteria have both RNA and DNA. The bacteria’s genomic chromosome is composed of DNA, as are any extrachromosomal plasmids. The RNAs may be transcripts (i.e. templates for the translation of proteins) or untranslated elements such as ribosomal RNA or small RNAs involved in transcriptional regulation.

Detailed explanation-3: -Leuko virus contains both DNA and RNA.

Detailed explanation-4: -DNA is the main hereditary material, but some contain RNA too, e.g. retrovirus. RNA mostly plays the role of a messenger in higher organisms. Though both are nucleic acids, why is there a difference in functions? Scientists elucidate that, this is due to the difference between the chemical structure of DNA and RNA.

Detailed explanation-5: -In bacteria, RNA polymerase exists in two states. One form, known as the core enzyme, can catalyze RNA synthesis but is unable to bind to promoter targets in DNA. The second form of RNA polymerase, the holoenzyme, is capable of both RNA synthesis and promoter recognition.
