by binding directly to the bases on one of the strands.
b
by intercalating itself between the base pair stacks.
c
through the negatively charged phosphate groups.
d
through the hydroxyl group of the sugar molecule.

the double-helix secondary structure of DNA is true
or false.

- 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.arrow_forwardThe major reason that antiparallel beta-stranded protein structures are more stable than parallel beta-stranded structures is that: Select one: a. parallel ones are in a slightly less extended configuration than antiparallel strands. b. parallel ones do not have as many disulfide crosslinks between adjacent strands. c. parallel ones do not stack in sheets as well as antiparallel strands.

- 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.

In DNA the distance between the strands of the double helix is relatively constant. B. The growing DNA polymer is synthesized in the 5' to 3' direction. C. The enzymes that catalyze DNA synthesis are known as DNA polymerases. D. RNA strands are synthesized in the 3' to 5' direction. E. Unlike DNA, RNA is easily cleaved because the 2'-OH group of the ribose is a nucleophile that catalyzes hydrolysis of the strand.arrow_forwardWhat is the effect of incubating a mixture of RNA and DNA with 0.1 M NaOH?
