The systematic oppression of one or more socially defined "races" by another socially defined "race" that is justified in terms of the supposedly inherent biological superiority of the rulers and the supposed inherent biological inferiority of those they rule is >

Racism

Explanation:

Racism is a social evil that has been prevailing since the start of mankind. It is a biasing against the people belonging to a particular group in the society where they are treated as inferior and the other people are considered superior to them.  

These distinctions are because of the following factors – color of skin, languages, customs and rituals, birth place etc. The western world has been very racist against the non-westerners.    

i think it is true in my reasonment ..

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.
