25) the hydrogen bond donor atom is one as it is ADENINE MOLECULE WHICH HAS NH2 SIDE CHAIN THAT FORM HYDROGEN BOND.
26)as one turn of alpha helix contain 3.6 amino acid residues . The marked amino acid is 2 helix previous than 100 .
So 2*3.6= 7.2 about 7.
So it will be 100-7 = 93 number amino acids.thank you

1. The figure below shows a DNA double helix and its nucleotide
sequence.
A. A homodimeric helix–turn–helix protein binds to a DNA
fragment containing this sequence. Its preferred half-site is
AACAC. Show where the two recognition helices in the protein
contact the DNA.
B. Are protein–DNA contacts primarily in the major or the minor
groove of DNA? What parts of the nucleotides contact the amino acid
side chains of the protein to provide most sequence specificity?

You have identified a novel activator protein. You assume that
like other activators, your protein has activation and DNA binding
domains. You carry out deletion analysis on the part of the ORF
that codes for the C-terminal end of your activator and assay both
DNA binding and transcription. You obtain the results indicated in
the figure below. Answer the following 3 parts (i,ii, &
iii) based on this information.
