Answer:
A mutation that causes a single letter change in the DNA sequence can affect your protein structure and function because the sequence of letters in a gene determines the sequence of amino acids in the protein that it encodes. A single letter change in the DNA alters the mRNA which alters the amino acid sequence of the resulting protein and sometimes that can cause serious results if it changes the way a protein works.
ex. sickle cell disease - a single letter swap in the gene that encodes the hemoglobin molecule results in deformed red blood cells
Hope that helps.
There are two types of alveolar cells. The type I alveolar cells which lines the alveoli and much more abundant than type II alveolar cells. Then the type II alveolar cells lesser in number but functions differently than type I alveolar cells. Type II alveolar cells secrete surfactant (composed of lecitin and sphingomyelin) for the lungs. Surfactant reduces the surface tension inside the alveoli, preventing alveolar consolidation. This is important as babies with dysfunctional type II alveolar cells (usually preterm babies less than 32 weeks age of gestation) will have respiratory distress syndrome in the absence of surfactant.
The correct option for the above statement is:
C. There is a water-loving side outside the cell.
Explanation:
The lipid bilayer is formed in such the simplest way that the hydrophobic facet is on within| and therefore the water affectioned (hydrophilic) facet is on the surface and inside.
It is a two-layered arrangement of phosphate and macromolecule molecules that is kind of cytomembrane, the hydrophobic macromolecule ends facing inward and therefore the hydrophilic phosphate ends facing outward.
