How do DNA molecules differ from RNA molecules?
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 base pairing is slightly different since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine.
Which is not a difference between RNA and DNA?
The correct answer is (c) DNA contains alternating sugar-phosphate molecules whereas RNA does not contain sugars.
Which of the following correctly describes A difference between DNA and RNA?
Which of the following correctly describes a difference between DNA and RNA? DNA occurs in the nucleus, whereas RNA only occurs outside the nucleus. DNA contains a ribose, whereas RNA contains a deoxyribose sugar. DNA contains four nucleotides, whereas RNA contains three.
In which ways is RNA different from DNA select all of the properties that apply to RNA but not DNA?
It differs from DNA chemically in two respects: (1) the nucleotides in RNA are ribonucleotides—that is, they contain the sugar ribose (hence the name ribonucleic acid) rather than deoxyribose; (2) although, like DNA, RNA contains the bases adenine (A), guanine (G), and cytosine (C), it contains the base uracil (U) …
Which of the following correctly describes a difference between DNA and RNA?
How are DNA and RNA molecules alike and different in their structure and functions?
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). Secondly, DNA is double-stranded while RNA is single stranded. Thirdly, DNA is more structurally stable compared to RNA.
Why is DNA molecule more stable genetic material than RNA?
Due to its deoxyribose sugar, which contains one less oxygen-containing hydroxyl group, DNA is a more stable molecule than RNA, which is useful for a molecule which has the task of keeping genetic information safe. RNA, containing a ribose sugar, is more reactive than DNA and is not stable in alkaline conditions.
What are the differences between DNA and RNA?
RNA is very unstable and decomposes rapidly. RNA is almost always single stranded. DNA and RNA use a ribose sugar as a main element of their chemical structures, ribose sugar used in DNA is deoxyribose, While RNA uses unmodified ribose sugar.
What is the structure of RNA nucleotides?
The structure of RNA nucleotides is very similar to that of DNA nucleotides, with the main difference being that the ribose sugar backbone in RNA has a hydroxyl (-OH) group that DNA does not. This gives DNA its name: DNA stands for deoxyribonucleic acid.
Why is RNA less hydrophobic than DNA?
RNA is more polar and therefore less hydrophobic than DNA because of the increased polarity of the extra hydroxyl group in ribose compared to deoxyribose. This means that DNA is more stable than RNA, because the strands are harder to separate because they are more attracted to each other than the surrounding water.
What type of sugar is in DNA and RNA?
Sugar Both DNA and RNA are built with a sugar backbone, but whereas the sugar in DNA is called deoxyribose (left in image), the sugar in RNA is called simply ribose (right in image).
