So, you want to start with the ear. And do the back and do the other ear. The ear is always kind of up tall. Then you start with the face.
Operon. Definition. noun, plural: operons. A group of genes or a segment of DNA that functions as a single transcription unit. It is comprised of an operator, a promoter, and one or more structural genes that are transcribed into one polycistronic mRNA.peron. Definition. noun, plural: operons.

The lac-operon is actually a series of adjacent genes and regulatory elements in one small part of the E. coli circular chromosome. Lac-Operon components Definitions: P strands for promoter; it is the site where RNA polymerase attaches in order to transcribe mRNA.hen the copies created heterozyous cells (I + , I -) normal regulation was observed. This indicated that the I gene codes for something that can move and interact with the operators of both copies of the lac-operon present in these cells.
