Talk:Lac operon
From Academic Kids
More info needed in this article. There seems to be more info on lac operon scattered around than here... Delta G 05:40, 4 Apr 2004 (UTC)
Someone should add the roll allolactose plays in the workings of the lac operon. DavidMendoza
What is the relation between lac operon and lac repressor
Does it mean that lac repressor is the protein transcribed from lac operon? --22:03, 3 Dec 2004 61.171.37.146
- The lac repressor is expressed from a gene, lacI, not within the lac operon. The lac operon produces one polycistronic mRNA which codes from three different proteins: lacZ, lacY, and lacA. LacZ is β-galactosidase which cleaves lactose, lacY is lactose permease which is a membrane protein to allow lactose to enter the cell, and lacA is transacetylase which has unknown purpose. The lac repressor is produced outside of the lac operon and binds to the operator in the lac operon, just upstream of the coding genes and downstream of the RNA polymerase binding site/promoter. Hope this helps. --G3pro 03:31, 4 Dec 2004 (UTC)
lac operon
The title of this article is incorrect. It should be lac operon. Let's remember correct convention. By using Lac operon the implication is that we are talking about a protein. Does anyone know how to change the way the title of the article looks? There were many instances of Lac being used to describe DNA or mRNA, try to use correct convention. lacI is the repressor gene or cistron, LacI is the repressor protein, this is one of the most basic rules of genetics/molecular biology.--Alun 17:53, 13 May 2005 (UTC)
