Answer: transcription, nucleus
Explanation:
In eukaryotic cell the process whereby the sequence of DNA bases is used to determine the sequence of bases in mRNA us called transcription and it occurs in the nucleus.
The DNA serves as the template strand. RNA polymerase binds to the promoter on the template DNA strand and synthesizes mRNA with RNA nucleotides. Genetic information of DNA is transcribed to messenger RNA. In eukaryotes this process occurs in the nucleus.
DNA is an acid that contains resources needed for development and function of every living thing, EVERY LIVING THING. even bacteria and viruses have DNA. without DNA there would be no life.
The phospholipid bilayer has two hydrophilic surfaces: the extracellular and the intracellular surfaces. These two layers sandwiches a major layer of lipids or fat. Because of this nature of the lipid bilayer, water-soluble or <em>hydrophilic</em> hormones cannot enter the cell membrane. They have to rely on the mechanisms of receptors.
One can find transmembrane proteins embedded across the whole length of the lipid bilayer. One of the functions of these proteins is to serve as the link for hormones such as the ones given above. When the water-soluble hormones attach to one of these receptors, the receptor will be activated and send down a signal to the intracellular environment; these signals will then travel down towards their target site and eventually activate whatever it is the hormone was made for. One example of these transmembrane proteins are <em>G-coupled proteins; </em>examples of signals that cascade down the cell are cylic AMP and cyclic GMP.
The ammonia has a higher molecular weight
