You are characterizing a DNA-binding protein, and have used genetic experiments to identify a domain required for the interaction of the protein with DNA. Your secondary structure analysis software predicts that the domain forms a β helix, but you are unconvinced. What experiments could you perform to confirm the presence of a β helix in this region?

If the %A of a bacteria is 30%, then the % (G+C) of the bacteria is 40% 2. The DNA is plectonemic because one of the strands go in 5' to 3' direction while the other go in the 3 to 5 direction

Which statements reflect the Watson-Crick model of DNA? Select all that apply. The strands of DNA run in the same direction. Two helical DNA strands are coiled around a common axis, forming a right-handed double helix. The sugar-phosphate backbone lies outside of the helix. The diameter of the helix is 30 Å.

For entertainment on a Friday night, a genetics professor proposed that his children diagram a polynucleotide strand of DNA. Having learned about DNA in preschool, his 5-year-old daughter was able to draw a polynucleotide strand, but she made a few mistakes. The daughter’s diagram (represented here) contained at least 10 mistakes. a. Make a list of all the mistakes in the structure of this DNA polynucleotide strand. b. Draw the correct structure for the polynucleotide strand.
In Watson and Crick's model of DNA structure, the two strands of the DNA double helix are joined through a. Ionic bonds b. Hydrophobic interactions c. Covalent bonds d. Disulfide bonds e. Hydrogen bonds
