What is found in DNA but not in RNA?
Where DNA has thymine, RNA has uracil. So the structural component that is found in DNA but not in RNA is thymine.
Is ribose in DNA or RNA?
Unlike DNA, RNA in biological cells is predominantly a single-stranded molecule. While DNA contains deoxyribose, RNA contains ribose, characterised by the presence of the 2′-hydroxyl group on the pentose ring (Figure 5).
What is the type of sugar present in DNA?
DNA’s sugar, deoxyribose, has five carbon atoms, which are connected to each other to form what looks like a ring.
What is true about DNA but not RNA?
Explanation: RNA contains uracil, while DNA contains thymine. All of the other statements are true. Note that DNA is usually double-stranded and RNA is usually single-stranded, but both can exist in the opposite configuration under certain conditions.
Which of the following is the sugar found in RNA that is different from DNA?
Daniel Nelson. The sugar found in RNA is ribose, whereas the sugar found in DNA is deoxyribose, both of which are 5-carbon sugars.
Which of the following is found in DNA but not in RNA quizlet?
DNA contains uracil, whereas RNA contains thymine.
Is ribose sugar found in DNA?
Two types of pentose are found in nucleotides, deoxyribose (found in DNA) and ribose (found in RNA).
Which sugar is present in DNA or RNA?
The sugar units present in natural DNA and RNA are D-2-deoxyribose and D-Ribose.
What type of sugar is found in RNA?
Unlike DNA, RNA is usually single-stranded. Additionally, RNA contains ribose sugars rather than deoxyribose sugars, which makes RNA more unstable and more prone to degradation. RNA is synthesized from DNA by an enzyme known as RNA polymerase during a process called transcription.
Which nitrogenous base is found in DNA but not found in RNA?
Dna, Rna, And Proteins : Example Question #1 Explanation: Uracil is a nitrogenous base that is only found in single-stranded RNA—it is not found in DNA. Thymine pairs with adenine in DNA, whereas in RNA, uracil pairs with adenine.
Is phosphate in DNA or RNA?
Both DNA and RNA contain one, two or three phosphate groups, attached to the 5′ carbon of the pentose sugar.
How does DNA differ from RNA?
There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.
What nitrogenous base is part of DNA but not RNA quizlet?
The correct answer is Uracil. Uracil is one of the four nitrogenous bases found in RNA. The other three nitrogenous bases in RNA are also found in DNA, but uracil is not found in DNA.
How are the sugars found in DNA and RNA different?
The five-carbon sugar in DNA is called deoxyribose, while in RNA, the sugar is ribose. These two are very similar in structure, with just one difference: the second carbon of ribose bears a hydroxyl group, while the equivalent carbon of deoxyribose has a hydrogen instead.
Is glucose in DNA or RNA?
One of the primary differences between DNA and RNA is that RNA has a specific sugar that DNA does not. RNA has the sugar ribose in it.
How is the sugar in RNA different from the sugar in DNA?
Is pentose sugar present in DNA?
The pentose sugar in DNA is called deoxyribose, and in RNA, the sugar is ribose. The difference between the sugars is the presence of the hydroxyl group on the 2′ carbon of the ribose and its absence on the 2′ carbon of the deoxyribose.
Is ribose sugar present in DNA?
The pentose sugar present in DNA is ribose.
What is the sugar of RNA?
Also, the sugar in RNA is ribose instead of deoxyribose (ribose contains one more hydroxyl group on the second carbon), which accounts for the molecule’s name. RNA consists of four nitrogenous bases: adenine, cytosine, uracil, and guanine.
