Which type of RNA has thymine?
Uracil
Uracil and thymine have very similar structures; uracil is an unmethylated form of thymine. The nucleotide sequence of RNA, which is complementary to the DNA sequence, allows RNA to encode genetic information….RNA Structure.

Is thymine DNA RNA or both?
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).
Where is thymine found?
DNA
Thymine is one of the pyrimidine bases found in the nucleic acid of deoxyribonucleic acid (DNA), along with adenine, guanine, and cytosine (A, G, and C, respectively). These bases are the building blocks of DNA and all life forms on earth.
Is thymine present in DNA?
Thymine (T) is one of four chemical bases in DNA, the other three being adenine (A), cytosine (C), and guanine (G). Within the DNA molecule, thymine bases located on one strand form chemical bonds with adenine bases on the opposite strand.
Which of the following contains thymine?
Thymine is present in RNA but not in DNA. Thymine is present in RNA but not in DNA.
What does thymine pair with in RNA?
Figure 3: DNA (top) includes thymine (red); in RNA (bottom), thymine is replaced with uracil (yellow). When this base-pairing happens, RNA uses uracil (yellow) instead of thymine to pair with adenine (green) in the DNA template below. Interestingly, this base substitution is not the only difference between DNA and RNA.
Why is there thymine in DNA and uracil in RNA?
DNA uses thymine instead of uracil because thymine has greater resistance to photochemical mutation, making the genetic message more stable. Outside of the nucleus, thymine is quickly destroyed. Uracil is resistant to oxidation and is used in the RNA that must exist outside of the nucleus.
Why is thymine not used in RNA?
Which base in place of thymine is present in RNA?
Four different types of nitrogenous bases are found in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G). In RNA, the thymine is replaced by uracil (U).
Is thymine A purine?
Nitrogenous bases present in the DNA can be grouped into two categories: purines (Adenine (A) and Guanine (G)), and pyrimidine (Cytosine (C) and Thymine (T)). These nitrogenous bases are attached to C1′ of deoxyribose through a glycosidic bond.
