Agene is a segment of dna that provides the instruction for making a protein. that specific protein that is made will influence our specific traits / characteristics along with the many physiological occurrences that take place within the human body. a gene will direct the synthesis of a protein by a two step process the first step transcription if the gene in the dna. transcription will first produce a messenger rna (rna) molecule. during transcription the sequence of bases in dna are used as a template construct a corresponding sequence of bases in the mrna.) describe what occurs in the nucleas during transcription
