How do DNA and RNA differ 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. During transcription, the enzyme RNA polymerase binds to DNA and separates the DNA strands.
What are 2 ways in which DNA differs from RNA?
First of all, the nucleotides of DNA and RNA are different: in DNA, in fact, pentose sugar is deoxyribose, while in RNA it is ribose, which has one more oxygen atom. Moreover, in DNA the nitrogen bases are adenine, cytosine, guanine and thymine while in RNA instead of thymine there is the uracil base.
Which do DNA and RNA have in common?
Both DNA and RNA have four nitrogenous bases each—three of which they share (Cytosine, Adenine, and Guanine) and one that differs between the two (RNA has Uracil while DNA has Thymine).
How are DNA and RNA different in function?
DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA is stable under alkaline conditions, while RNA is not stable. DNA and RNA perform different functions in humans.
Which is a better nucleic acid DNA or RNA?
DNA is a more stable nucleic acid. RNA, on the other hand, contains a ribose sugar and is more reactive than DNA. Therefore, DNA is a better genetic material than RNA. Put your understanding of this concept to test by answering a few MCQs.
What’s the difference between RNA and prokaryotes?
RNA has a simpler structure and is needed in order for DNA to function. Also, RNA is found in prokaryotes, which are believed to precede eukaryotes. RNA on its own can act as a catalyst for certain chemical reactions. The real question is why DNA evolved, if RNA existed.
How are the bases and sugars of RNA different?
Composition of Bases and Sugars deoxyribose sugar phosphate backbone adenine, guanine, cytosine, thymine bases ribose sugar phosphate backbone adenine, guanine, cytosine, uracil bases Propagation DNA is self-replicating. RNA is synthesized from DNA on an as-needed basis.
