WebGenes are composed of deoxyribonucleic acid ( DNA ), except in some viruses, which have genes consisting of a closely related compound called ribonucleic acid ( RNA ). A DNA molecule is composed of two chains of nucleotides that wind about each other to resemble a twisted ladder. WebThe five genes that are needed to synthesize tryptophan in E. coli are located next to each other in the trp operon. When tryptophan is plentiful, two tryptophan molecules bind the repressor protein at the operator sequence. This physically blocks the RNA polymerase from transcribing the tryptophan genes.
