Also, are all genes expressed all the time? No! This will not only lead to wastage of cellular energy but also affect the balance within acell. This is why gene expression is regulated. How exactly are genes regulated? Let’s find out. ...
we examined single-cell RNA-seq (scRNA-seq) data from the healthy human lung epithelial cells42to check whether the expression repression of ISGs is also a lineage-specific phenomenon that could be observed in PNECs rather than being cancer-specific. Consistent with the ...
How Is Gene Expression Regulated? The amounts and types of mRNA molecules in a cell reflect the function of that cell. In fact, thousands of transcripts are produced every second in every cell. Given this statistic, it is not surprising that the primary control point for gene expression is ...
网络调节型基因表达 网络释义 1. 调节型基因表达 调节型基因表达(regulated gene expression)是指基因表达受环境及生理状态的调控。它可分为诱导和阻遏两种类型。 press.ustc.edu.cn|基于 1 个网页
DNA会和histone protein打包成为chromatin然后反复(按照Todd的理论,这就是套娃,)压缩成mitotic chromosome。这里我们就知道DNA一般不至于裸奔,而是以chromatin的形式存在。Chromatin又可以简单地分成两组hetero-chromatin (densely packed) - generepression和euchromatin (open and accessible) - geneexpression。
At low miRNA:target-RNA ratios, gene expression is regulated posttranscriptionally via RISC. After loading of miRNAs into RISC, miRNA:target-RNA duplexes form on the basis of sequence complementarities, resulting in target RNA cleavage. Amplification of the miRNA signal by transitive siRNAs occurs....
Alternative splicing is a regulated process during gene expression that results in a single gene coding for multiple proteins The Genetic Code The genetic code consists of 64 triplets of nucleotides. These triplets are called codons.With three exceptions, each codon encodes for one of the 20 amino...

At present there is little information on the regulatory processes by which the chorionic gonadotropin (CG)/LH receptor gene is regulated in ...
