LASER-wikipedia2 Control of an operon is a type of gene regulation that enables organisms to regulate the expression of various genes depending on environmental conditions. 控制操縱子基因是屬於基因調節(regulation of gene expression)的一種,能使生物調控不同基因對環境條件的表現。 LASER-wikipedia2...
Transcription is the first step of gene expression; this produces anmRNAsequence from the genetic information in the coding sequence of the gene. Then, the produced mRNA sequence undergoes processing in order to remove non-coding sequences. After the processing of the mRNA molecule, it leaves the...

There really wasn’t any reason to imagine that there were any other kinds of molecules necessary, other than proteins, to carry out everything that’s done in a cell—especially with regard to the regulation of gene expression. The complexity of gene regulation by proteins alone was so ...

Thus, gene expression could be considered a measure of activity for a gene within a particular cell. This short video of Prof Nick Spitzer will hopefully help you to understand gene expression: Using the GTEx database, the kiwi/Aussie researchers were able to explore the levels of GBA expressi...
leaf cells undergo dramatic changes in cell metabolism, structure, and gene expression. The most striking feature of these changes is that the decomposition of chlorophyll during chloroplast denaturation results in the yellowing of leaves, followed by hydrolysis of macromolecules such as lipids, proteins...
One transcription factor that affects multiple lineages is, GATA-2, a transcriptional factor that recognizes the tetranucleotide sequence GATA, a nucleotide motif in target genes. A functional GATA-2 gene, which specifies this transcription factor, is essential for the development of the lymphoid, er...
