This is because the electrons are up around the oxygen more than they are around the hydrogen. The electrons are spinning around but they're around the oxygen more than they are around the hydrogen. This makes them polar because they have a charge on one end of the molecule. In a nonpolar molecule electrons are evenly distributed.
The lac repressor functions as a tetramer and requires binding of all four sites before it releases because first it assures that the lactose level is high before the operon turns on for further steps.
<h3>
What is Lac Repressor ?</h3>
Lac repressor is a type of protein. It prevents the transcriptional stages of genes which involved in the Lactose utilization. Lac Operon binds to the DNA at a particular site which is known as Operator. Operator is the downstream of the promoter and the upstream of the site of transcription.
Lac repressor is made up of 2 DNA binding subunits which are composed of 2 monomers each and the monomers have particular 4 distinct regions.

Answer:
1. anabolic, amphibolic, anaplerotic and catabolic.
2. acetyl-CoA and oxaloacetate---- reactants
citrate, CoA-SH and heat -------products
4a. pyruvate carboxylase.
Explanation:
An anabolic process is a type of process in which complex biomolecules are formed from simpler molecules. The amphibolic pathway is a biochemical pathway that consists of both catabolic and anabolic processes. An anaplerotic process is a type of process that replenishes the stores of citric acid cycle intermediates. A catabolic process is the process by which complex molecules are broken down to simpler ones.
acetyl-CoA and oxaloacetate are the reactants whereas citrate, CoA-SH and heat are the products of citrate synthase reaction of the citric acid cycle.
Pyruvate carboxylase is an enzyme catalyzes and conversion of pyruvate to oxaloacetate.
Lung Cancer is the leading cause of cancer deaths in women, killing more women each year than breast cancer, ovarian cancer, and uterine cancer. Patients diagnosed with early stages of Hodgkin Lymphoma have a 90 - 95 % survival rate. But out of this list, the most curable cancer is Ovarian cancer. Ovarian cancer has an average of fewer than 200,000 cases per year and 7.2 per 100,000 deaths in women per year.
Hi there,
It is because of Nucleic Acid.
