Respuesta :
The answer is Thymine.
—Evidence—
Within the DNA molecule, adenine bases located on one strand form chemical bonds with thymine bases on the opposite strand.
—Evidence—
Within the DNA molecule, adenine bases located on one strand form chemical bonds with thymine bases on the opposite strand.
By means of hydrogen bonds, the nucleic acid thymine bonds with adenine in a section of double-stranded DNA.
What are nucleic acids?
Nucleic acids are the monomer units of DNA which is composed of long chains of nucleic acids linked together by phosphodiester bonds as well as by hydrogen binds between two DNA strands.
In double-stranded DNA molecule, the nucleic acid adenine bonds with thymine, while guanine bonds to cytosine through hydrogen bonds.
Therefore, thymine bonds with adenine in a section of double-stranded DNA.
