Gene regulation in eukaryotic cells is regulated by repressors as well as by transcriptional activators. Like their prokaryotic counterparts, eukaryotic repressors bind to specific DNA sequences and inhibit transcription. Any step of gene expression may be modulated, from the DNA-RNA transcription step to post-translational modification of a protein. The following is a list of stages where gene expression is regulated, the most extensively utilised point is Transcription Initiation: Chromatin domains.
Change/transformed
Explanation:
Igneous rocks can be transformed or changed to form metamorphic rocks in the presence of elevated pressure and temperature.
Metamorphic rocks are also called changed rocks in which a rock protolith especially from igneous or sedimentary rocks is transformed.
- In igneous rocks, minerals are recrystallized to form new ones
- The metamorphic rocks contain minerals that typifies them.
- Some metamorphic rocks can be formed at elevated pressure alone with increasing burial.
- Some can from through contact metamorphism where high temperature is the determining re-crystallization factor.
- Most metamorphic rocks form under conditions of high temperature and pressure.
- Examples of metamorphic rocks are schist, gneiss, talc etc.
