Thymine will tend to hydrogen bond with adenine in DNA due to complementary base pairing. In RNA, uracil can also hydrogen bond with adenine.
a hydrogen bond
An H-bond, or known as hydrogen bond. Hydrogen bonds are attractive bonds, very strong but easy to break. Think of it as someone who has a girlfriend(a strong bond, connected) but is attracted to other girls. A hydrogen bond is not as strong as a covalent or ionic bond(a strong bond).
(Adenine and Thymine) or (Guanine and Cytosine) are the respective molecules which join by hydrogen bond to attach to the double strand of DNA.
The chemical bond that holds together the complementary nucleotide bases in DNA is called a hydrogen bond. These bonds form between specific pairs of bases (A-T and G-C) and help stabilize the double helix structure of the DNA molecule.
If you are talking about between the bases of DNA, then it is a Hydrogen bond. A hydrogen bond will break easily for replication when the helicase separates the DNA.
When mRNA separates from DNA, the bond that is broken is a hydrogen bond.
Hydrogen bonds form between the nitrogenous bases of a DNA molecule. These hydrogen bonds connect adenine with thymine (or uracil in RNA) and guanine with cytosine, contributing to the double helix structure of DNA.
Thymine will tend to hydrogen bond with adenine in DNA due to complementary base pairing. In RNA, uracil can also hydrogen bond with adenine.

A double hydrogen bond binds adenine and thymine
A hydrogen bond is the attractive interaction of a hydrogen atom with an electronegative atom, like nitrogen , oxygen or fluorine (thus the name "hydrogen bond", which must not be confused with a covalent bond to hydrogen). The hydrogen is covalently bonded to another electronegative atom. The energy of a hydrogen bond (typically 5 to 30 kJ/mole) is comparable to that of weak covalent bonds (155 kJ/mol), and a typical covalent bond is only 20 times stronger than an intermolecular hydrogen bond. These bonds can occur between molecules (intermolecularly), or within different parts of a single molecule (intramolecularly). [2] The hydrogen bond is stronger than a van der Waals interaction , but weaker than covalent , or ionic bonds . This type of bond occurs in both inorganic molecules such as water and organic molecules such as DNA.

The complementary DNA base sequence that would bond with ATGT is TACA. In DNA, adenine pairs with thymine, and guanine pairs with cytosine. This follows the base pairing rules of DNA.
