NEET Chemistry Nucleic Acids MCQ Question
DNA and RNA differ in the sugar component of their nucleotide structure. If the molecular weight of 2-deoxyribose is approximately 134 g/mol, what is the approximate molecular weight of ribose in RNA?
150 g/mol
144 g/mol
134 g/mol
126 g/mol
Correct Answer
Detailed Explanation
Ribose in RNA has one more oxygen atom than 2-deoxyribose in DNA. The additional oxygen increases the molecular weight of ribose by approximately 16 g/mol, making it around 144 g/mol.
