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.
Answer:
The nucleus contains the cell 's DNA and directs the synthesis of ribosomes and proteins. ... Ribosomes are large complexes of protein and ribonucleic acid responsible for protein synthesis when DNA from the nucleus is transcribed.

Energy stored in food can be used by cells to add a phosphate group to ADP to make ATP. This cycling of ATP to ADP occurs in a metabolic process called cellular respiration. phosphate group breaks, and energy is released. ATP becomes ADP, and the cycle of storing and releasing energy continues until the cell dies.
