You are required to know the molecular structures for deoxyribose, ribose as well as a nucleotide, DNA and RNA. You may be asked to draw one or more of these five molecules. Be prepared to compare (sameness and similarities) and contrast (differences) DNA and RNA molecules.
Understand the Problem
The question is asking to identify and draw the molecular structures for deoxyribose, ribose, a nucleotide, DNA, and RNA. It also requires a comparison and contrast of DNA and RNA molecules.
Answer
DNA: deoxyribose, thymine, double-stranded. RNA: ribose, uracil, single-stranded.
DNA and RNA are nucleic acids composed of nucleotides, consisting of a sugar, phosphate, and nitrogenous base. DNA uses deoxyribose, is double-stranded, and has thymine. RNA uses ribose, is single-stranded, and has uracil instead of thymine.
Answer for screen readers
DNA and RNA are nucleic acids composed of nucleotides, consisting of a sugar, phosphate, and nitrogenous base. DNA uses deoxyribose, is double-stranded, and has thymine. RNA uses ribose, is single-stranded, and has uracil instead of thymine.
More Information
DNA and RNA are crucial for genetic information storage and protein synthesis. Despite their structural similarities, the presence of deoxyribose and ribose sugars distinguishes their functions and stability.
Tips
A common mistake is confusing the sugars and nitrogenous bases between DNA and RNA.
