The repressor protein is coded by the i gene.
<h3>What is the function of the repressor protein in lac operon?</h3>
A protein known as a repressor prevents one or more genes from being expressed. The i gene codes for the repressor protein. The repressor protein inhibits messenger RNA synthesis by attaching to the promoter region of the gene(s). For the control of gene expression in cells, repressor proteins are crucial.
Repressors and activators of gene expression in bacteria are different from one another. However, depending on how a DNA binding protein interacts with other proteins in the cell or in other biological contexts, higher eukaryotic cells can use it as either an activator or a repressor of gene expression. As repressors, additional components like non-coding RNA may also be present.

Answer:
D) Tight junctions
Explanation:
Based on the information provided within the question it can be said that the structure that performs this function are known as tight junctions. This structure has two different functions. The first being to limit the passage of molecules and ions through the space between cells, and the second function is that is blocks the movement of important membrane proteins between the epithelial cells
Answer: Tt
Why? Heterozygous mean two different genotypes, meaning you need both dominant and recessive. So Tt
Hope this helps :D
The answer is c)lysosome . Because lysosome is the organelle that contains, digestive enzymes. It's responsible for digesting food.It can also be used, when a cell needs to be destructed. The process of a cell destructing itself is called "autolysis" , lysosome is used in this process.
