Complementary sequences of DNA, which pair the nucleotide base adenine with thymine, and cytosine with guanine, are held together by hydrogen bonds.
The nucleotide bases are partially made up of nitrogen, oxygen and hydrogen molecules bonded together. On each base, one nitrogen is bonded to a hydrogen. Nitrogen is very electronegative, meaning that it pulls hydrogen's electron closer to it and becomes slightly negative. This leaves a slightly positive hydrogen sticking out.
Each base also has an oxygen sticking out with a pair of electrons ready for bonding. These electrons can not bond with hydrogen, as hydrogen is already in a bond with nitrogen and can only form one bond. However, they are negatively charged and strongly attract the slightly positive hydrogen on the opposite complimentary base.
This pattern means that two hydrogen bonds are formed each pair of complementary bases, holding complementary sequences together.

Does introns have complementary sequences in DNA?
Introns do not have specific complementary sequences in DNA. Introns are non-coding regions of a gene that are removed during the process of mRNA splicing. Their removal allows for the exons (coding regions) to be joined together to form the mature mRNA transcript.
What would the base sequences on the other strand of Dna be?
They would be described as being complementary - as in complementary base pairing.
Examples of palindromic DNA sequences?
Some examples of palindromic DNA sequences are "GGTACC" (complementary sequence: "CCTAGG"), "ACGT" (complementary sequence: "TGCA"), and "AGCT" (complementary sequence: "TCGA"). These sequences read the same on both strands when read in the 5' to 3' direction.
The two strands of DNA molecules are held together by?

A search for sequences that are complementary to the desired sequence of a DNA fragment uses a technique called?
The technique used to search for sequences that are complementary to a desired sequence of a DNA fragment is called "sequence alignment." This process involves comparing the sequences to find regions of similarity or complementarity. Various bioinformatics tools and software are available to assist in this process.
What kind of good is consumed together like peanut butter and jelly?
Complementary goods are consumed together.
Which bases are complementary to one another how are they held together in the double helix of DNA?
In DNA, adenine pairs with thymine and guanine pairs with cytosine, forming complementary base pairs. These pairs are held together by hydrogen bonds, with A-T forming two hydrogen bonds and G-C forming three hydrogen bonds. This complementary base pairing is essential for the stability and replication of the DNA molecule.
How are complementary nitrogenous bases held together?
Complementary nitrogenous bases are held together by hydrogen bonds. Adenine pairs with thymine (or uracil in RNA) by forming two hydrogen bonds, while cytosine pairs with guanine by forming three hydrogen bonds. These hydrogen bonds provide the necessary stability for the base pairing in DNA and RNA molecules.
