Complementary DNA bases are connected to one another through hydrogen bonds. These bonds form between specific pairs of bases: adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). This pairing is essential for the structure and function of DNA molecules.

Which enzyme is responsible for adding complementary DNA bases to an exposed DNA strand?
The enzyme responsible for adding complementary DNA bases to an exposed DNA strand is DNA polymerase.
How are the two complementary strands of DNA connected to each other?
The two complementary strands of DNA are connected to each other through hydrogen bonds between the nitrogenous bases. This bond forms a double helix structure, with adenine pairing with thymine and cytosine pairing with guanine.
. How are complementary strands of DNA held together?
Complementary strands of DNA are held together by hydrogen bonds connecting complementary bases.
What are the bases of mRNA coded for by this section of DNA before the mutation?
The bases of mRNA coded for by a DNA segment are complementary to the original DNA sequence. If the DNA sequences are ATCG, the corresponding mRNA bases will be UAGC.
What type of bond holds the two sides of the DNA molecule together?
DNA is a double-stranded molecule twisted into a helix (think of a spiral staircase). Each spiraling strand, comprised of a sugar-phosphate backbone and attached bases, is connected to a complementary strand by non-covalent hydrogen bonding between paired bases. The bases are adenine (A), thymine (T), cytosine (C) and guanine (G). A and T are connected by two hydrogen bonds. G and C are connected by three hydrogen bonds.
