Which nitrogen containing base is found in RNA but not in DNA?
Uracil 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.
Which of the following is found in RNA but not in DNA?
Answer and Explanation: The nitrogenous base that is found in RNA but not in DNA is c. uracil. Additionally, RNA contains a sugar known as ribose.
What nitrogenous base is found in RNA but not in DNA Brainly?
Uracil Uracil is the nitrogenous base present only in RNA, but not in DNA. Thymine is in DNA.
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.
Why is uracil present in RNA but not DNA?
Uracil is energetically less expensive for the production of thymine. This can account for its utilization in RNA. Damage to DNA can change the nucleotide bases causing mutations that cannot be repaired if the base was uracil.
What nitrogenous base is 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.
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).
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.
Is guanine in DNA or RNA?
Adenine and guanine are found in RNA and DNA in terrestrial life, whereas thymine is only found in DNA and uracil only in RNA.
Which nitrogenous base is found in RNA but not in DNA Brainly?
Uracil Uracil is the nitrogenous base present only in RNA, but not in DNA. Thymine is in DNA.
Which nitrogenous base is not present in DNA?
So the correct answer is 'Uracil'.
Is cytosine in DNA or RNA?
Cytosine is a pyrimidine, and one of the nitrogenous bases found in ribonucleic acid (RNA) and deoxyribonucleic acid (DNA).
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.
Is uracil in DNA or RNA?
Uracil (U) is one of the four nucleotide bases in RNA, with the other three being adenine (A), cytosine (C) and guanine (G). In RNA, uracil pairs with adenine. In a DNA molecule, the nucleotide thymine (T) is used in place of uracil.
Which of the following bases is found only in RNA?
Uracil is found only in RNA and not in DNA.
