Question
Chapter 3, Problem 11TYU
Summary Introduction
To explain:
What type of amino acids are present in the DNA-binding region of proteins.
Concept introduction:
DNA-binding proteins are a specific type of protein that contain DNA-binding domains. They possess a high affinity toward single or double-stranded DNA molecules. These DNA-binding proteins interact with DNA molecules at a major or minor groove of the DNA structure. These proteins help in modulating the function of DNA, for example, transcription.

- Suppose that DNA did not have a double helix structure, and instead DNA was single-stranded. Imagine that a cell with this single-stranded DNA was ready to begin cell division.
