Autoradiogram is a term that is commonly used in the field of molecular biology. It is a technique that is used to visualize the distribution of radioactive isotopes within a biological sample. This technique is widely used in the study of DNA, RNA, and protein synthesis, as well as in the field of medical imaging.
Definitions
An autoradiogram is a photographic image produced by exposing a photographic film or other light-sensitive material to a sample that has been labeled with a radioactive isotope. The resulting image shows the distribution of the radioactive isotope within the sample.
Origin
The term autoradiogram comes from the Greek words “auto,” meaning self, “radios,” meaning radiation, and “gramma,” meaning something written or drawn. The term was first used in the early 1950s by scientists who were studying the properties of radioactive isotopes.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, an autoradiogram is “a photographic image produced by exposing a photographic film or other light-sensitive material to a sample that has been labeled with a radioactive isotope.”
The Oxford English Dictionary defines an autoradiogram as “a photographic image produced by the action of radiation emitted by a radioactive substance on a photographic emulsion.”
Associations
The technique of autoradiography is often used in the study of DNA, RNA, and protein synthesis. It is also used in the field of medical imaging, particularly in the diagnosis and treatment of cancer.
Synonyms
Some synonyms for autoradiogram include radiograph, radiogram, and radiographic image.
Antonyms
There are no direct antonyms for autoradiogram, but some related terms include non-radioactive imaging techniques such as magnetic resonance imaging (MRI) and computed tomography (CT) scanning.
The same root words
Some related terms that share the same root words as autoradiogram include radiology, radiation, and radiography.
