transcription requires a specific combination of transcription factors
Explanation:
Combinatorial control refers to a regulatory mechanism in eukaryotic transcription that involves several transcriptional factors. Simply saying, in eukaryotes, expression of a gene is controlled by specific combinations of transcriptional factors. This also means that one factor can be involved in regulation of two distinct genes but in combination with different other factors.
Combinatorial control is one of the examples which shows the complexity of gene regulation in eukaryotes over the prokaryotes.
LPS is lipopolysaccharide located in the outer membrane (OM) of the unique lipid bilayer ofGram-negative bacteria. Gram-negative bacteria containins Lpt or the lipopolysaccharide transport systems which is responsible for transporting LPS. It consists of seven known LPS transport proteins.
