DNA backboneb. hydrogen bondsc. the centromered. base complementaritye. DNA polymerasef. covalent bonds4. Analysis of hte bases of a sample of nuclic acid yielded these percentages: A 20%, G 30%, C 20%, T 30%. The sample could be5. Which of the following is not true about a linear molecule of double-stranded DNA?a. Pentose sugars are linked via covalent phosphodiester bondsb. At one end, two 5′ phosphate groups can be foundc. It is a double helix composed of antiparallel strandsd. Bases are paired via hydrogen bonds6. In the Hersey-Chase experiment, T2 phage were radioactively labeled with either 35S or 32P, and allowed to infect E. coli. What results were proved that DNA was the genetic material?a. The 35S was found in progeny phage, and the 32P was found in phage ghostsb. The 32P was found in both progeny phage and in phage ghostsc. The 35S was found in phage ghosts, and the 32P was found in progeny phaged. The 35S was found in both progeny phage and in phage ghosts7.
