Phonetic Transcription

/kɪs.trɒn/

Meaning and Usage

A "cistron" refers to a specific segment of genetic material (like DNA) that functions as a unit within a gene; it is often associated with the production of proteins. In molecular biology, cistrons are crucial for understanding gene expression and the regulation of biological functions.

Cistrons are generally used in scientific discourse, particularly within genetics and molecular biology. The usage of this term is more common in written contexts, such as academic papers, research articles, and textbooks.

Frequency of Use

The frequency of use is relatively low, as it is a specialized term primarily used by scientists and researchers in genetics.

Example Sentences

1. The researcher isolated a specific cistron that plays a crucial role in protein synthesis.

2. Исследователь выделил конкретный цистрoн, который играет ключевую роль в синтезе белка.

3. Mutations in the cistron can lead to significant changes in an organism's phenotype.

4. Мутации в цистрoне могут привести к значительным изменениям в фенотипе организма.

5. Understanding the function of each cistron is essential for genetic engineering.

6. Понимание функции каждого цистрoна является важным для генной инженерии.

Idiomatic Expressions

The term "cistron" is not commonly found in idiomatic expressions due to its technical nature. However, it can be associated with phrases related to genetics such as "gene expression," "gene regulation," and "DNA sequencing." Below are some example sentences related to genetic idioms:

1. Researchers diligently study gene regulation to understand how cistrons influence traits in organisms.

2. Исследователи тщательно изучают регуляцию генов, чтобы понять, как цистрoны влияют на характеристики организмов.

3. The discovery of a novel cistron could revolutionize our understanding of genetic diseases.

4. Открытие нового цистрoна может произвести революцию в нашем понимании генетических заболеваний.

5. When observing cistron behavior in various organisms, we can identify patterns in heredity.

6. Наблюдая за поведением цистрoна у различных организмов, мы можем выявить закономерности наследования.

Etymology

The term "cistron" was coined in the 1960s derived from the combination of "cis-" (referring to a position or relationship in genetics) and "tron" (which is often used in biological terms to denote units or particles). It specifically signifies a segment of DNA that encodes a single polypeptide chain.

Synonyms and Antonyms

Synonyms

• Gene
• Genetic unit

Antonyms

• Transcription unit (as it refers to larger portions of DNA that may contain several cistrons).
• Non-coding DNA (which does not code for proteins).
