<span>Hersey and Chase labeled the outer protein coat of a bacteriophage with radioactive sulfur, and the inner DNA with radioactive phosphorous. After allowing the bacteriophage to infect E.coli bacterium and undergoing a heavy blender process, the empty "ghost" phages were separated from the bacteria. The infected E.coli were positive for radioactive phosphorous, indicated that DNA was the genetic material inserted from the bacteriophage. The radioactive sulfur was not present in the infected bacteria, indicating that protein was not the genetic material.</span>

2. The DNA double helix. The two sides are the sugar-phosphate backbones, composed of alternating phosphate groups and deoxyribose sugars. The nitrogenous bases face the center of the double helix.

3. A nucleotide is an organic molecule that is the building block of DNA and RNA. ... A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.

4. A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.

5. In genetics, the term junk DNA refers to regions of DNA that are non-coding. Some of this noncoding DNA is used to produce noncoding RNA components such as transfer RNA, regulatory RNA and ribosomal RNA
