異染色質的意思、翻譯和例句

是什麼意思

「異染色質」是指細胞核內的一種染色質形式,與常規的染色質(通常稱為「常染色質」)相比,異染色質在細胞分裂時呈現出更深的染色反應,通常被認為是基因不活躍的區域。異染色質的主要功能包括保護基因組的完整性、調控基因表達,以及維持細胞的結構穩定性。異染色質可以分為兩種主要類型:構造異染色質和功能異染色質。

  1. A part of the cell's DNA that is not active.
  2. A type of DNA that does not make proteins.
  3. A section of DNA that is tightly packed.
  4. A form of DNA that is less accessible for gene expression.
  5. A type of chromatin that is mostly inactive in terms of gene activity.
  6. A region of chromatin that is densely packed and often transcriptionally silent.
  7. A structural form of chromatin that plays a role in gene regulation and chromosomal stability.
  8. A chromatin state associated with gene repression and genomic integrity.
  9. A specialized form of chromatin that is crucial for maintaining genome stability and regulating gene expression.
  10. A tightly packed form of chromatin that is generally not involved in active transcription.

1:Heterochromatin

用法:

這是異染色質的正式名稱,指的是細胞核內一種特殊的染色質結構。它通常呈現為深染色,並且在細胞分裂時保持緊緊包裹的狀態,這使得它的基因表達受到抑制。異染色質在基因調控、細胞分裂和基因組的穩定性方面扮演著重要角色。

例句及翻譯:

例句 1:

異染色質在細胞核中通常位於邊緣,並且不參與基因表達。

Heterochromatin is usually located at the periphery of the nucleus and does not participate in gene expression.

例句 2:

在某些細胞類型中,異染色質的比例較高,這可能影響細胞功能。

In certain cell types, the proportion of heterochromatin is higher, which can affect cell function.

例句 3:

異染色質的結構使其在細胞分裂期間保持穩定。

The structure of heterochromatin allows it to remain stable during cell division.

2:Inactive chromatin

用法:

用於描述那些不參與基因轉錄的染色質區域。這些區域通常是緊密包裝的,並且不易被轉錄因子接觸,因此無法進行基因表達。這種狀態的重要性在於它能夠幫助維持基因組的穩定性和防止不必要的基因表達。

例句及翻譯:

例句 1:

不活躍的染色質在基因調控中扮演著至關重要的角色。

Inactive chromatin plays a crucial role in gene regulation.

例句 2:

在細胞週期的某些階段,不活躍的染色質可能會轉變為活躍狀態。

During certain phases of the cell cycle, inactive chromatin may transition to an active state.

例句 3:

研究顯示,不活躍的染色質可以影響基因的表達模式。

Studies show that inactive chromatin can influence gene expression patterns.

3:Condensed chromatin

用法:

這是描述染色質在細胞分裂期間的緊密包裝狀態。當細胞準備分裂時,染色質會凝縮成可見的染色體,這一過程是細胞分裂的關鍵部分。凝縮的染色質有助於保護基因組並確保在細胞分裂時正確分配。

例句及翻譯:

例句 1:

在有絲分裂期間,染色質會凝縮成明顯的染色體。

During mitosis, chromatin condenses into visible chromosomes.

例句 2:

凝縮的染色質確保了基因在細胞分裂過程中的穩定性。

Condensed chromatin ensures the stability of genes during cell division.

例句 3:

研究人員觀察到,凝縮的染色質在基因表達中扮演著重要角色。

Researchers have observed that condensed chromatin plays an important role in gene expression.
