Radioactive probes are molecules that are labeled with a radioactive isotope, such as ^32P or ^35S, which emit radiation that can be detected. They are commonly used in molecular Biology to detect specific DNA, RNA, or protein molecules by binding to complementary sequences and producing a signal that can be visualized.
cDNA probes are used in molecular biology to detect and quantify specific RNA sequences through hybridization techniques. They are synthesized from complementary DNA (cDNA) based on mRNA templates, allowing for the study of gene expression. By labeling cDNA probes with fluorescent or radioactive tags, researchers can visualize and analyze the presence and abundance of specific genes in various biological samples. This technique is crucial for understanding gene regulation, function, and the effects of various treatments on gene expression.
Yes, the Voyager missions were run by NASA and they sent the probes.
Space probes typically use solar panels to provide energy. These panels convert sunlight into electricity to power the spacecraft's instruments and systems. In some cases, radioisotope thermoelectric generators (RTGs) are also used to generate power through the decay of radioactive isotopes.
Some space probes currently in space include the Parker Solar Probe, Juno (studying Jupiter), and the Voyager probes (Voyager 1 and Voyager 2) which are now in interstellar space. These probes are conducting various studies and missions related to planetary exploration and scientific research.
Space probes are not piloted. Probes are launched to places that are months or years away in travel time. A pilot would require too much food, air, and water.
To make DNA probes
Nonradioactive probes are DNA or RNA molecules labeled with a chemical or enzyme for detection in molecular biology experiments. These probes are used in applications such as Southern and northern blotting, in situ hybridization, and PCR for identifying and detecting specific nucleic acid sequences without the need for radioactive materials. They provide a safe and cost-effective alternative to radioactive probes for molecular detection techniques.
Radioactive probes are useful for DNA fingerprinting because they can bind specifically to complementary DNA sequences, allowing scientists to visualize the DNA fragments on an X-ray film. This helps in identifying unique DNA patterns and comparing them between individuals for forensic or paternity testing purposes. Additionally, radioactive probes are highly sensitive and can detect small amounts of DNA, making them a powerful tool for genetic analysis.
Probes for cloned genes are usually short, single-stranded DNA or RNA molecules that are complementary to specific sequences in the cloned gene. These probes are labeled with a detectable marker, such as a fluorescent dye or a radioactive isotope, to allow for visualization and identification of the gene. The probes can be used in techniques like Southern blotting or in situ hybridization to detect the presence and location of the gene in a sample.
fluorescent dyes, radioactive isotopes, or enzymes. These labels enable visualization and quantification of the gene sequences in a sample.
The Pioneer and Voyager space probes primarily used radioisotope thermoelectric generators (RTGs) as their energy source. These RTGs convert the heat released from the decay of radioactive isotopes, typically plutonium-238, into electricity, allowing the probes to operate over long periods in the cold, dark regions of the outer solar system. This method provided a reliable and long-lasting power supply, essential for the probes' extended missions.
Some radioactive metals are advantageous because they are useful. Certain radioactive metals like cobalt-60 are used as gamma ray sources for portable X-ray equipment, and to sterilize foods and other products. The most common use of radioactive metals is the use of uranium in nuclear reactors, principally to generate electric power. Radioactive metals are used as thermoelectric generators in space probes that travel far from the sun (because solar panels won't work far out). And these are just a few of their uses.

Space probes would be safer.
These are called probes. They are labeled with a radioactive element and designed to bind specifically to the complementary sequence of the target clone fragment. By detecting the radioactive signal emitted by the probe binding to the target fragment, researchers can identify and locate the specific clone of interest in a large population.
