How Do You Spell EXPRESSION LIBRARY?

Pronunciation: [ɛkspɹˈɛʃən lˈa͡ɪbɹəɹi] (IPA)

The spelling of "expression library" can be a bit tricky because of the various sounds it includes. In IPA phonetic transcription, it is spelled /ɪkˈsprɛʃən ˈlɪbrəri/. The first syllable has the short "i" sound, followed by a "k" and "s" blend. The second syllable includes the "e" sound, followed by a retroflex "sh" and a schwa. The final two syllables both have the "i" sound, followed by a "b" and "r" blend and ending with a short "i" sound.

EXPRESSION LIBRARY Meaning and Definition

1. An expression library is a collection or database of cloned DNA fragments that represent the entire transcriptome or specific set of genes from an organism. These DNA fragments, known as cDNAs (complementary DNAs), are derived from the reverse transcription of mRNA molecules isolated from cells or tissues. The process of creating an expression library involves synthesizing cDNA using reverse transcription and then inserting these cDNA fragments into a suitable vector, which often includes a promoter region for expression. The resulting library contains a diverse range of cDNAs that correspond to the genes expressed in the original sample.

   The purpose of an expression library is to facilitate the study of gene expression patterns and the identification of specific genes or gene products. Researchers can extract the cDNA clones from the library and analyze their sequences, allowing them to investigate the genes expressed in a particular tissue or during specific biological processes. By comparing expression libraries from different conditions, researchers can identify genes that are upregulated or downregulated under specific circumstances.

   Expression libraries have also been widely used in the field of recombinant DNA technology to produce large quantities of specific gene products. This technique involves screening the expression library to isolate clones that express a desired protein. These clones can then be cultured and used to produce the protein of interest in large quantities for research or commercial purposes.

   In summary, an expression library is a valuable resource that enables the analysis of gene expression patterns, the identification of novel genes, and the production of specific gene products.

Etymology of EXPRESSION LIBRARY

The term "expression library" is derived from two words: "expression" and "library".

1. Expression: The term "expression" comes from the Latin word "expressio" which means "a representing, manifestation, or presentation". It stems from the Latin verb "exprimere" which means "to press out, squeeze out, or extract". Over time, "expression" has come to refer to the act of conveying or representing one's thoughts, ideas, or feelings through various means such as language, art, or behavior.

2. Library: The word "library" comes from the Latin word "liber" which means "book" or "bookcase". It originally referred to a collection of written or printed works that were stored and made available for reading or reference. The concept of a library has evolved to include other forms of media, such as audio, video, and digital resources.
