DNA is the ultimate control of cell's productions. So A.
Answer: missense
Explanation:A missense mutation is a type of mutation in which there is a change in one single nucleotide in a DNA sequence which results in an altered mRNA sequence and consequent incorporation of wrong amino acid into the amino acid sequence of a protein. The single nucleotide change in DNA results in a different codon on the mRNA sequence and this leads to production of a protein that is different from the original protein. This change can affect the function of the protein, in most cases it makes the protein nonfunctional.
Human placental lactogen( hPL) hormone released during fetal development is primarily responsible for preparing breasts for lactation.
- Human placental lactogen also stimulates milk ,known as human chorionic somatomammotropin. It's made by the placenta. It gives nutrition to the fetus. secretion of milk is called lactation
- Mother milk contains all the nutrients that an child needs in the first 6 months of life, including fat, carbohydrates, proteins, vitamins, minerals and water. It's fluently digested and efficiently used. secretion of milk is called lactation. bone milk also contains bioactive factors that compound the child's immature vulnerable system, furnishing protection against infection, and other factors that help digestion and immersion of nutrients. mother milk also protect the child from disease.

Given what we know, we can confirm that If a single protein carries out multiple functions, then each function may be carried out by a specific region of the protein called a domain.
<h3>What is a domain in proteins?</h3>
This is one of the many parts that make up a protein. This is what we can call the most independent parts of a protein given that they are each self-stabilizing and form their own three-dimensional structures. Each domain of a protein is considered a functional group, and therefore a single protein can carry out multiple functions.
Therefore, we can confirm that for a protein like the one described in the question, the multiple functions being carried out can be explained by the presence of the domain regions of the protein.
