Which of the following statements are correct for transcription factor binding to DNA? (no explanation needed) Select one or more: A- Transcription factors can only bind to DNA when they are phosphorylated. B- By analyzing the amino acid sequence of a transcription factor, we can determine which DNA sequence it will bind. C- When transcription factors bind to DNA, specific amino acid side chains form bonds with functional groups of the nucleotide bases in the DNA. D- For transcription factors to bind to DNA, a helicase first needs to unwind the DNA double helix. E- Some transcription factors can have either activatory or suppressive effects, depending on promoter context and binding partners.
