What information does a phase diagram give

Basically a phase diagram represents the different phases of any substance with the range of temperature and pressure in which these phases exists. It also represents the transition stages and the existsing substances in the transition stages with their phase state

A phase diagram provides a plethora of information in the form of graphs. It basically shows when a certain substance changes its form into a different stage of the matter. It has two axes and with these axes, it accurately represents the exact points where the temperature and pressure change into different states of matter. There is also a triple point where you can see a spot with all three states of matter that exist for an element and this only occurs when the temperature and the pressure are at a certain point, which differs for every element.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
