Concept explainers
(a)
Interpretation:
Deoxy thymidine:
It is a pyrimidine deoxynucleoside which pairs with adenine in double stranded DNA. It consists of thymine and deoxyribose sugar.
Concept introduction:
Thymine combined with deoxyribose to form the nucleoside deoxythymidine which is the same as thymidine.
To determine: The base and sugar in deoxythymidine
(b)
Interpretation:
Adenosine is both a chemical found in many living systems and a medication. It plays a key role in regulation of blood flow to various organs through vasodilation.
Concept introduction:
Adenine combined with ribose to form adenosine. It is generally found in nature and play an important role in biochemical process.
To determine: The base and sugar in adenosine
(c)
Interpretation:
Cytidine is a nucleoside that is composed of the base cytosine linked to the five carbon sugar D-ribose. It is a component of RNA with molecular mass and chemical formula .
Concept introduction:
Cytosine combines with ribose ring to form cytidine. It is a component of RNA.
To determine: The base and sugar in cytidine.
(d)
Interpretation:
Deoxyguanosine is very similar to guano sine with one hydroxyl group removed from the position of the ribose sugar.
The structure of deoxyguanosine is
Concept introduction:
Guanine combines with deoxyribose sugar to form deoxyguanosine.
To determine: The base and sugar in deoxyguanosine.

The dominant macrostate or configuration of a system is the macrostate with the greatest weight W. Are both statements correct?arrow_forwardFor the single step reaction: A + B → 2C + 25 kJ If the activation energy for this reaction is 35.8 kJ, sketch an energy vs. reaction coordinate diagram for this reaction. Be sure to label the following on your diagram: each of the axes, reactant compounds and product compounds, enthalpy of reaction, activation energy of the forward reaction with the correct value, activation energy of the backwards reaction with the correct value and the transition state. In the same sketch you drew, after the addition of a homogeneous catalyst, show how it would change the graph. Label any new line "catalyst" and label any new activation energy.arrow_forward
