The nitrogenous bases form hydrogen bonds between opposing DNA strands to form the rungs of the "twisted ladder" or double helix of DNA or a biological catalyst that is found in the nucleotides. Adenine is always paired with thymine, and guanine is always paired with cytosine. These are known as base pairs.
<span>As humans change the way we live on the planet, the way that nitrogen moves around the Earth also changes. Nitrogen atoms may seem small enough to be easily overlooked. We look right through the ones in the air, do we not? Yet recent changes in the nitrogen cycle are causing a very noticeable effect on natural environments and human health. Lakes are clogged with aquatic weeds. Dead zones have formed in areas of the oceans where animals can not survive. Air pollutants that contain nitrogen are decreasing air quality and greenhouse gases that contain nitrogen are becoming more common.</span>

Hey, there!!
There is no place for virus, virions, prions in kungdom classification. The reason is they show both living and non living characters, which don't define them whether they are living beings or non living things.
As in 5 kingdoms, the only living organisms are classified.
- Kingdom Monera mostly deals with the organism which contains prokaryotic cells.
- Kingdom Protista deals with the organism which have eukaryotic cells.
- Kingdom Fungi deals with various fungal organism.
- Kingdom Plantae deals with various type of plants.
- Kingdom Animalia deals with various type of animals.
So, you can see that there is non of the kingdoms which deals with the organism which have similar characteristics like viruses, virions and prions.
