Detailed explanation-1: -The virus has a single strand of a nucleic acid, but she does not know if it is DNA or RNA. After running tests, she concludes that it is DNA. Which of the following would lead her to that conclusion? It contains uracil.
Detailed explanation-2: -RNA can direct the creation of proteins and perform other essential functions of life that DNA can’t do. RNA’s versatility is one reason that scientists think this polymer came first, with DNA evolving later as a better way to store genetic information for the long haul.
Detailed explanation-3: -What would MOST likely happen if a genetic defect prevented the cell from producing one or more of these enzymes? Replication would stop until more enzyme was produced. Potentially hazardous mutations would accumulate in the cell.
Detailed explanation-4: -Which of the following characteristics of Figure 1 best shows that the fragment is RNA and not DNA? Which of the following best describes a structural difference between DNA and RNA? The backbone of DNA contains deoxyribose, whereas the backbone of RNA contains ribose.
