Answer:
The given blank can be filled with operator.
Explanation:
The proteins that assist in turning on or turning off the function of a specific gene by getting combined with certain sections of the DNA are known as transcription factors. The transcription factors that activate the transcription of a specific gene are known as activators, while that prevents transcription and is termed as repressors.
A repressor can be an RNA or a DNA binding protein, which prevents the articulation of genes by getting combined with the operator. A repressor, which binds with DNA prevents RNA polymerase from getting combined with the promoter, which further inhibits the transcription of the genes into mRNA.
The type of rock that will be formed is METAMORPHIC ROCK.
Metamorphic rocks are pre-existing rocks that are formed as a result of physical or chemical alteration by mean of heat and pressure. The process transform the rock into a denser, more compact rock. Examples of metamorphic rocks are marble, gneiss and schist. Metamorphic rocks can be formed from already existing igneous or sedimentary rock. <span />
