Answer: Gene is defined as a segment of DNA ( deoxyribonucleic acid) that codes for a particular protein and the protein thus formed corresponds to a specific trait ( like eye color) of the organism.
Genes are passed from parents to their offsprings and in this way specific traits are inherited by offsprings from their parents.
Genes are located on the chromosomes ( thread like structures composed of DNA).
It makes sense that cell membranes are made of phospholipids because water cant mix in with lipids, so the phospholipids will be able to effectively block out any unwanted water or chemicals suspended in water outside of the cell.
