Complementary base pairing.
Diploid cells
a DNA molecule has two paired strands. ~
Complementary base pairing occurs only between the probe and the target gene.
The probe is the second strand of DNA that forms double-stranded DNA with the target gene.
The complementary base pairing between DNA strands enables hybridization between a labeled probe and a target gene. The hydrogen bonding between adenine-thymine and guanine-cytosine base pairs allows the probe to specifically bind to its complementary sequence in the target gene, facilitating detection.
A probe will hybridize to a target gene due to complementary base pairing between the nucleotides of the probe and the target sequence. This specificity allows the probe, often labeled for detection, to bind to its complementary region on the target gene under appropriate conditions, such as temperature and salt concentration. The hybridization process is driven by the stability of the double-stranded DNA formed, which is influenced by factors like sequence complementarity and the presence of chemical modifications. This property is widely utilized in techniques such as PCR, microarray analysis, and in situ hybridization for gene detection and analysis.
A Gene Probe is a term used to label several techniques used to identify a Gene Loci. a gene probe is often a piece of genetic material, that mirrors the target gene, and is also 'tagged' with dye so it can be identified.
We design probes to be specific so that they will hybridize only to the target gene but not to random, unrelated genes. A probe hybridizes to a sequences to which it is complementary to. Consequently, the longer the probe is, the more specific it will be.

The complementary base pairing between adenine (A) and thymine (T), and cytosine (C) and guanine (G) allows a single-stranded DNA probe to hybridize with a single-stranded target gene. This specificity is key for detecting and identifying specific sequences in the target gene through base pairing interactions.
A probe can find a single-stranded target DNA gene apex by hybridizing to its complementary sequence. This is often achieved through techniques like fluorescence in situ hybridization (FISH) or polymerase chain reaction (PCR), where the probe is labeled with a fluorescent tag or a reporter molecule. The specificity of the probe ensures that it binds only to the target sequence, allowing researchers to detect and analyze the gene of interest among other genetic material.
