Which base is found in RNA but not in DNA quizlet?

Which base is found in RNA but not in DNA 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.

What are the different bases found in RNA?

RNA consists of four nitrogenous bases: adenine, cytosine, uracil, and guanine. Uracil is a pyrimidine that is structurally similar to the thymine, another pyrimidine that is found in DNA.

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.

Is thymine in DNA or RNA?

Figure 3: DNA (top) includes thymine (red); in RNA (bottom), thymine is replaced with uracil (yellow). Three of the four nitrogenous bases that make up RNA — adenine (A), cytosine (C), and guanine (G) — are also found in DNA.

Which base is only in RNA?

Uracil 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.

How is RNA different from DNA?

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 are the four 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.

How does RNA differ from DNA quizlet?

How is RNA different from DNA? RNA is different from DNA is three ways: (1) the sugar in RNA is ribose not dioxyribose; (2) RNA is generally single-stranded and not double-stranded; and (3) RNA contains uracil in place of thymine.

How are the bases in DNA and RNA different?

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. Uracil differs from thymine in that it lacks a methyl group on its ring.

Which is not found in DNA?

Uracil is unique in RNA. It is not found in DNA. Instead of uracil in DNA, thymine is present. But thymine is absent in RNA.

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.

What does RNA have that DNA doesn t?

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). This hydroxyl group make RNA less stable than DNA because it is more susceptible to hydrolysis.

What is the difference between DNA and RNA in terms of bases?

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. Uracil differs from thymine in that it lacks a methyl group on its ring.

What does RNA contain that DNA does not?

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 are three ways RNA differs from DNA?

RNA differs from DNA in several ways. First of all, RNA is single-stranded, not double-stranded….Figure 19.6.

  • A Ribonucleotide. …
  • The 5-Carbon Sugar Ribose. …
  • The Four Nitrogenous Bases in RNA: Adenine, Guanine, Cytosine, and Uracil. …
  • A Phosphate Group.

What is the base not found in DNA?

Uracil Explanation: Uracil is a nitrogenous base that is only found in single-stranded RNA—it is not found in DNA.

What base is not found in RNA?

In RNA, the base thymine is not found and is instead replaced by a different base called uracil, abbreviated U. The other three bases are present in both DNA and RNA.

How does RNA different from DNA?

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 are the 3 differences between RNA and DNA?

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 is difference between RNA & DNA?

DNA is a double-stranded molecule that has a long chain of nucleotides. RNA is a single-stranded molecule which has a shorter chain of nucleotides. DNA replicates on its own, it is self-replicating. RNA does not replicate on its own.

Which base is only found in RNA?

Uracil Uracil is the nitrogenous base present only in RNA, but not in DNA. Thymine is in DNA. DNA have thymine, guanine, adenine and cytosine. Thymine is replaced by uracil in RNA.
