If a DNA-binding protein reads a short stretch of DNA and detects the following second genetic code provided by the functional groups located on each base as H-HD-CH3-HA-HA-HA-HA-HD, then what is the corresponding sequence of bases? a. CGGAb. CAGAc. CTGAd. CTAG

The answer is C. CTGA

Explanation:

DNA-binding proteins are proteins that have DNA-binding domains and thus have a specific or general affinity for single - or double-stranded DNA.

In this case, when the proteins bind, it detects CTGA (Cytosine, Thymine, Guanine, and Adenine) which happens to be the building blocks that make up genes and as such it spells out the exact order of a protein's building blocks.
