What role do insulator sequences play in the regulation of eukaryotic transcription?

What role do insulator sequences play in the regulation of eukaryotic transcription?

What role do insulator sequences play in the regulation of eukaryotic transcription? They block binding of transcription factors to enhancers. They block communication between enhancers and nontargeted promoters. They block binding of transcription factors to cis-acting promoter elements.

What are the characteristics of an insulator?

Insulators have strong bonds that hold their particles rigidly in place. Since particles in an insulator don’t move around easily, the amount of energy that is transferred to other particles is minimal. This prevents particles from gaining energy and increasing the temperature.

Is a vacuum the best insulator?

Why is vacuum insulation considered the best known insulator? Vacuums serve as high performance thermal barriers to prevent heat transfer due to thermal conduction and convection. “With its complete lack of atoms, a vacuum is often considered to be the best known insulator.”

What makes a bad insulator?

What are bad insulators? Materials like glass and plastic are poor electrical conductors, and are called insulators. They are used to stop electricity from flowing where it is not needed or where it can be dangerous, such as through our bodies. Cables are wires covered in plastic so we can handle them safely.

What is the least effective insulator?

Paper, glass, plastic and Styrofoam are common materials used in containers holding hot beverages. Considering containers of the same size, a glass container is the least effective for keeping a cup of coffee warm.

Is air a good insulator of electricity?

An insulator (such as plastic, rubber, or glass) can have 1020x the resistivity of a metal like copper. Air (like in the atmosphere) is actually an excellent electrical insulator. This means that electricity can be sent through a conductor and it won’t jump through the air.
