Video Transcript. My name is Michael and I'm an artist. And I'm going to show you how to draw a husky. You want to start with the ears. Huskies have very alert ears, very tall ears. 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.

Prokaryotes tend to control their gene expression at the transcriptional level, often through the use of operons. An operon is a group of genes that functions together and is regulated together. A classic example of this is the lac operon, which was first discovered in e.coli.The lac operon in e.3.3 Explain the steps involved in the process of protein synthesis and how genetic expression is controlled in prokaryotes and eukaryotes by regulatory proteins (e.g., the role of operons in prokaryotic cells; the mechanism of gene expression in eukaryotic cells).
