The<u> repressor </u>is a type of regulator protein that binds to a region of DNA in the promoter of a gene called the operator and prevents transcription from taking place.
In the field of science, a regulator protein can be described as a kind of protein that affects the transcription of a gene by having an influence on particular DNA sites. The rate of synthesis of various proteins is controlled by the regulator proteins.
A repressor is a kind of regulator protein that prevents the transcription of a particular gene. When the rate of a protein in the body has reached normal, the transcription of the protein needs to be stopped in order for more protein of that kind to be formed. The repressor binds itself to the operator region for the gene, hence stopping the transcription process until the protein is required again.

Ribosomes are the building blocks of trna, that are produced in the mitochondria, aka the powerhouse of the cell
Answer:
2
Explanation:
There are no zeros so the only numbers there are is 2 and 3. So two numbers equals two sig figs.
Answer:
DNA, found within the nucleus, must be replicated in order to ensure that each new cell receives the correct number of chromosomes.
A relatively large molecule that has an electrical charge associated with it, regardless if it is full charge or partial. Would require facilitated diffusion to enter a cell.
Eg - complex sugars, or disaccharides - fructose, or amino acids, ions - Na + or Ca +.
