Which protein complex directs dna bending into loops that contact rna polymerase and transcription factors bound at the core promoter or with protein complexes bound to proximal promoter elements?

Answer :Enhanceosome
Protein complex that binds enhancer elements and directs DNA bending into loops that bring the protein complex into contact with RNA polymerase and transcription factors bound at the core promoter or with protein complexes bound to proximal promoter elements.

enhanceosome a large protein complex formed by the aggregation of multiple proteins, a few binding enhancer sequences and others binding other proteins.

They direct DNA bending into loops that bring the enhanceosome into contact with RNA polymerase and transcription factors bound at the core promoter or with protein complexes bound to proximal promoter elements.

The DNA loops can be small or large, in keeping with the observation that enhancers many be close to or quite distant from the genes they regulate.

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
