It's uracil, which replaces thymine in RNA.
One difference between DNA and RNA is that DNA has a nitrogen base pyrimidine thymine that connects with purine adenine. In RNA, thymine is replaced by another pyrimidine called uracil.
In RNA, there are four kinds of base: adenine, guanine, cytosine and uracil. There are no thymine bases. Therefore, there are no thymine and adenine base pairs. Addtional answer: The complimentary base of adenine in RNA is uracil which is a unmenthylated form of thymine. When menthylation occurs it becomes thymine which is paired with adenine in DNA. Thymine can also be called 5-methyluracil because it becomes thymine when methylation of uracil occurs at the 5th carbon.
In RNA, the nitrogenous bases change and there is no longer Thymine, instead Uracil replaces Thymine but it bonds with the same base pair ( Adenine) as it would in DNA. In other words DNA base pairs are : Adenine- Thymine, Guanine-Cytosine. RNA base pairs are : Adenine- Uracil, Guanine-Cytosine.
Thymine can be converted into uracil through a process called deamination, where the methyl group on thymine is removed to form uracil. This process is carried out by enzymes called deaminases. Conversely, uracil can be converted into thymine by adding a methyl group to uracil, a process facilitated by enzymes called methyltransferases.
The DNA sequence of gene that change AACTTG to AACATG are called missense mutation. This is known as a process.
The base that replaces thymine in RNA is called uracil. Uracil is structurally similar to thymine but lacks a methyl group. This difference allows RNA to play a complementary role during gene expression as well as in other cellular processes.

It will use adenine, but thymine will be replaced by a nitrogen base called "uracil" in mRNA
Adenine only binds with Thymine, and Guanine only binds to Cytosine in DNA. In RNA however,Thymine is replaced with Uracil which binds to Adenine.
There is no particular phobia for being replaced, but there are similar phobias that are similar: Autophobia - fear of being alone or by oneself. Metathesiophobia - fear of changes.

Adenine always pairs with thymine in DNA.

The nucleotides used to build DNA are Adenine, Cytosine, Guanine, and Thymine. For RNA, there is no Thymine; it is replaced with another nucleotide called Uracil. These are actually the names of the nitrogenous bases that nucleotides contain. A nucleotide is made up of a Deoxyribose Sugar, a Phosphate Molecule, and a Nitrogenous Base. We refer to them though by the name of their nitrogenous base.
Thymine can be converted into uracil through a process called deamination, where the methyl group on thymine is removed to form uracil. This process is carried out by enzymes called deaminases. Conversely, uracil can be converted into thymine by adding a methyl group to uracil, a process facilitated by enzymes called methyltransferases.
The bulkheads structurally support the hull.
for DNA, Thymine (T) is used, whereas for RNA, Uracil (U) is used, but not Thymine.
