Document Summary
13. 1 experiments using bacteria and viruses demonstrated that dna is genetic material they performed experiments in which they made the virus"s dna radioactive with. 32p, or they labeled its protein coat with 35s. They mixed radioactive virions with escherichia coli and incubated the mixture for a few minutes; this allowed the virions to attach to e. coli and initiate the infection process. Culture was then centrifuged to separate the infected cells from any unadsorbed phage particles: the results of their experiments showed that blender treatment did not disrupt the infection process, because progeny phages were produced. 13. 2 nucleic acid and protein structure: dna, rna, and proteins are often called informational molecules, dna is a polymer of deoxyribonucleotides. Deoxyribonucleic acid (dna) is a polymer of deoxyribonucleotides linked together by phosphodiester bonds. The monomers of dna are called deoxyribonucleotides because the sugar found in them is deoxyribose.
