In what ways do the chemical structures of DNA and RNA differ?
So, the three main structural differences between RNA and DNA are as follows: RNA is single-stranded while DNA is double-stranded. RNA contains uracil while DNA contains thymine. RNA has the sugar ribose while DNA has the sugar deoxyribose.
What are the 3 main structural differences between DNA and RNA?
1 Answer
- DNA:
- Sugar is deoxyribose sugar.
- Double stranded structure.
- Nitrogen bases are Adenine, Guanine, Cytosine and Thymine.
- RNA:
- Sugar is ribose sugar.
- Single stranded molecule.
- Nitrogen bases are Adenine, Guanine, Cytosine and Uracil.
What are the structural differences between RNA and DNA quizlet?
The three main differences between RNA and DNA is that (1) The sugar in RNA is ribose instead of deoxyribose, (2) RNA is generally single-stranded and not double-stranded , and (3) RNA contain uracil in place of thymine.
How do the structures of RNA and DNA differ quizlet?
Firstly, DNA is composed of a double strand forming a helix whereas RNA is only composed of one strand. Also the sugar in DNA is deoxyribose whereas in RNA it is ribose. Finally, both DNA and RNA have the bases adenine, guanine and cytosine. However DNA also contains thymine which is replaced by uracil in RNA.
What is the main functional difference between RNA and DNA?
DNA and RNA perform different functions in humans. DNA is responsible for storing and transferring genetic information, while RNA directly codes for amino acids and acts as a messenger between DNA and ribosomes to make proteins.
How are RNA and DNA similar How do they differ?
RNA uses the bases adenine, uracil, guanine, and cytosine. Uracil differs from thymine in that it lacks a methyl group. DNA and RNA serve different functions. DNA stores and transfers genetic information, while RNA acts as a messenger between DNA and ribosomes to make amino acids and proteins.
What are 4 differences between RNA and DNA?
DNA has four nitrogenous bases – Adenine, Guanine, Cytosine and Thyamine. RNA also has four nitrogenous bases, Adenine, Guanine, Cytosine and Uracil.
Which is not a difference between RNA and DNA?
Answer and Explanation: The correct answer is: (c) DNA contains alternating sugar-phosphate molecules whereas RNA does not contain sugars. See full answer below.
