(b)
Interpretation:
For each nucleotide, it is to be stated whether it can be part of RNA or DNA.
Concept introduction:
In both RNA and DNA, the backbone of a single strand consists of alternating sugar and phosphate group. In RNA, the sugar group is ribose whereas in DNA, it is deoxyribose. In the ribose sugar, the
(c)
Interpretation:
The nitrogenous base in each of the given nucleotides is to be identified.
Concept introduction:
Nucleotides are distinguished from one another by identifying the nitrogenous bases attached to the sugar group. In both RNA and DNA, it is the specific sequence of the nitrogenous bases that determines the genetic information that is stored or carried. There are four types of five nitrogenous bases that could be present in RNA and DNA. Uracil, guanine, adenine, cytosine, thymine are the nitrogenous bases present in RNA and DNA. In a nucleotide, the

Doxorubicin works by binding to DNA in such a way that a portion of it penetrates the DNA double helix— a process called intercalation. During transcription— the process that forms RNA— portions of the DNA strands are temporarily separated for the base sequence to be read and then are reconnected. With bound doxorubicin, however, the double helix does not reform properly after the strands are separated, which disrupts replication— the process that forms an identical copy of DNA. Which portion of doxorubicin do you think intercalates into the DNA double helix, and why do you think it has little difficulty doing so?arrow_forward
