The nitrogen forms many components like nucleic acids, proteins, amino acids etc. It is the inert gas and is the most abundant gas present in the atmosphere. It plays an important role in the fixation of nitrogen .They play a vital role in the formation of protoplasm. It is present in ...
Nitrogen is a critical life element and a major component of amino acids, nucleic acids, and other important biomolecules. Plants cannot directly use atmospheric nitrogen gas. Thus, nitrogen in the soil is transformed through the nitrogen cycle....

We quantified temporal variations in carbon (C) and nitrogen (N) content, starch, fructan and total soluble sugars in leaves, stem bases and roots of F. paniculata during one growth cycle in mown and unmown fields and related them to the dynamics of soil mineral N concentration and soil ...
access for their life cycle. Here we show that HIV-1 pseudotyped with VSV-G or native Env uses the same pathway as EVs after internalization into HeLa cells or primary CD4+T cells to deliver its content into the nucleus of host cells, a process that can be intercepted by chemical drugs...
