#Section 3: Genetics, Cellular and Molecular Biology

  1. binds tightly to a region of DNA thousands of base pairs away from the DNA to be transcribed.

  2. can synthesize RNA chains de novo (without a primer).

  3. has a subunit called lambda, which acts as a proofreading ribonuclease.

  4. separates DNA strands throughout a long region of DNA (up to thousands of base pairs), then copies one of them.
