This stored form of water is changed into liquid form and flows down through streams and used by plants and animals. But more increase in temperature causes rise of sea level which is not good for areas near the sea.
RNA synthesis depends on RNA polymerases (RNAPs). This is the enzyme
that faciliates copying a sequence of DNA which is the first step
leading to gene expression. This multi-step process is important for
researchers to understand especially in relations to studying how
genetics influence disease processes.
