Summary
Hybrid arrested translation is a method to identify DNA clones by blocking specific messenger RNA translation. This technique detects gene products by observing their absence in translation patterns, differing from hybrid selection.
Area of Science:
- Molecular Biology
- Biotechnology
- Genetics
Background:
- Hybrid arrested translation (HAT) is a technique used in molecular biology.
- It is used to identify recombinant DNA clones.
- This method is similar to hybrid selection or hybrid release.
Purpose of the Study:
- To describe the methodology and application of hybrid arrested translation.
- To differentiate HAT from hybrid selection/release.
- To highlight the utility of HAT in identifying gene products.
Main Methods:
- Utilizes the ability of DNA clones to hybridize with specific messenger RNA (mRNA) in a cell-free system.
- Prevents the translation of the targeted mRNA.
- Relies on the disappearance of a specific gene product from the translation pattern.
Main Results:
- Hybrid arrested translation allows for the identification of recombinant DNA clones.
- It enables the detection of specific gene products through the absence of their translation.
- This method provides a distinct approach compared to hybrid selection, which reveals one or a few polypeptides.
Conclusions:
- Hybrid arrested translation is an effective method for identifying gene products.
- The technique offers a unique way to study gene expression and function.
- HAT complements existing molecular biology techniques for clone identification.

01:44Termination of Translation
The large ribosomal subunit has several important structures essential to translation. These include the peptidyl transferase center (PTC) - which is the site where the peptide bond is formed - and a large, internal, water-filled tube through which the nascent polypeptide moves. This latter structure is called the Peptide Exit Tunnel, and it begins at the PTC and spans the body of the large ribosomal subunit. During translation, as the nascent polypeptide chain is synthesized, it passes through...

02:31In-situ Hybridization
In situ hybridization (ISH) is a technique used to detect and localize specific DNA or RNA molecules in cells, tissue, or tissue sections using a labeled probe. The technique was first used in 1969 for the investigation of nucleic acids. It is currently an essential tool in scientific research and clinical settings, especially for diagnostic purposes.

02:29Hybrid Zones
Hybrid zones are narrow regions where two closely related species interact, mate, and produce hybrids. Relative to either parent species, hybrids may possess distinct phenotypic or genetic differences that impact their survival and reproductive success. The genetic variances introduced by hybridization influence species diversity and speciation processes within the hybrid zone.Gene flow and natural selection are evolutionary mechanisms that shape the outcome of a hybrid zone. Gene flow...
02:07FISH - Fluorescent In-situ Hybridization
Fluorescence in situ hybridization, or FISH, was developed in the early 1980s and has quickly become one of the most widely used techniques in cytogenetics. Labeled probes are used to bind complementary DNA or RNA sequences on a chromosome or in a region within a cell. Earlier, the probes could only be obtained by cloning or reverse transcription of a DNA template. Currently, the probe oligonucleotides can be synthesized synthetically. Additionally, with the advancement of optical techniques,...
01:31Hybridoma Technology
Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.
