Q. 17.93 - An Introduction to General, Organic, and Biological Chemistry

Question

Identify the base and sugar in each of the following nucleo-sides

a. deoxythymidine

b. adenosine

c. cytidine

d. deoxyguanosine

Step-by-Step Solution

Answer

The answers to this questions is:

a) Base - Thymine Sugar - Deoxyribose

b) Base - Adenine Sugar - Ribose 

c) Base - Cytosine Sugar - Ribose

d) Base - Guanine Sugar - Deoxyribose

Part (a) Step 1: Given information

We have to tell base and sugar in the given nucleoside.

 deoxythymidine

Part (a) Step 2: Explanation

The nitrogenous base that deoxythymidine was derived from was the pyrimidine base thymine, and the sugar present was deoxyribose.

Base - Thymine Sugar - Deoxyribose

Part (b) Step 1: Given information

We have to find the base and sugar in the given nucleoside.

adenosine 

Part (a) Step 2: Explanation

The purine base adenine provided the nitrogenous base for the nucleoside adenosine, while the sugar present is ribose.
Base - Adenine Sugar - Ribose

Part (c) Step 1: Given information

We have to tell base and sugar in the given nucleo-side.

cytidine 

Part (c) Step 2: Explanation

The purine base adenine provided the nitrogenous base for the nucleoside adenosine, while the sugar present is ribose. 

Base - Cytosine Sugar - Ribose

Part (d) Step 1: Given information

We have to tell base and sugar in the given nucleo-side.

deoxyguanosine 

Part (d) Step 2: Explanation

The nitrogenous base that deoxythymidine was derived from was the pyrimidine base thymine, and the sugar present was deoxyribose.

Base - Guanine Sugar - Deoxyribose
