In a typical nucleotide the nitrogenous base is attached to carbon at:
Correct answer: A. Position 01 of pentose sugar
- A. Position 01 of pentose sugar
- B. Position 05 of pentose sugar
- C. Position 03 of pentose sugar
- D. Position 02 of pentose sugar
Explanation
In nucleotides, the nitrogenous base is always attached to the 1' carbon of the pentose sugar. This is a fundamental aspect of nucleotide structure. The 5' carbon is where the phosphate group binds, forming the backbone of the nucleic acid chain. The 3' carbon is crucial for the formation of phosphodiester bonds in the nucleic acid strand. The 2' carbon differentiates between ribose and deoxyribose sugars, affecting RNA and DNA respectively.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
