Answer:
b. Mainly between the conserved histone folds and the phosphate backbone of the DNA helix.
Explanation:
Histones are proteinous substances that are present in the chromatin of eukaryotic organisms.
The histones help to package or group DNA molecules in eukaryotic organisms into a structure that we refer to as chromosomes.
The contacts between the DNA and the histones of the nucleosome occurs mainly between the conserved histone folds and the phosphate backbone of the DNA helix.

Answer:
What role do transcription factors play in gene structure and function?
Transcription factors are proteins that bind to the upstream regulatory elements of genes in the promoter and enhancer regions of DNA and stimulate or inhibit gene expression and protein synthesis. They play critical roles in embryogenesis and development
