When lactose is not present, what happens to E. coli is that the genes that produce the enzymes needed to break down lactose are not expressed. The correct answer is B.
Answer:
The correct answer is - autosomal codominant inheritance (due to multiple alleles).
Explanation:
Autosomal codominant inheritance or codominance is a pattern of inheritance where the alleles present of an autosomal gene express their character in the phenotype. In other words, in this type of pattern, no allele would be masked by other alleles and both will be expressed in the phenotype.
The human ABO blood group is an example of this pattern as there are three alleles A, B, and O. In the heterozygous case of AB blood group both A, and B alleles expressed together however, O is masked by both alleles A, and O.
Answer: The receptor site is the location that a drug binds to, altering the function of a biomolecule.
Explanation:
The drug receptors site, are the sites where the sites where the drug molecules bind. Basically, a low number of receptors exists and the extent to which the molecules occupy their sites differ with the concentration of drug. The receptor site changes the conformation and function of the binding molecule of the drug.
