DNA replicates itself, so no, unlike what it may seem, parent organisms do not loose their DNA. Before the fecundation process, a cool process similar to miosis happens, it is called meiosis. During meiosis the parent chromosome will duplicate it self and break down each of its 46 chromosomes into 4 different new formed cells, which will become the sperm and egg cells. Each of these egg or sperm cells will be different from eachother, which is how you get siblings that don't look alike, however they will contain a copy of the parent's genetic information.
In conclusion;
In the creation of offspring, the copy of the parent's DNA breaks apart into 4 different pieces which will form sperm or egg cells.
Biochemistry can be defined as the study of chemical compounds that occur in living organisms (plants and animals), and the vital processes that occur in their metabolism and catabolism. Biochemistry combines elements from both biology and chemistry and it involves the study of large biological molecules such as proteins, carbohydrates and lipids, nucleic acids and enzymes in terms of their interactions, functions and structures. Biochemistry can be divided into three disciplines which are; protein science, molecular genetics, and metabolism.
Food is squirted from the stomach into the small intestine. Here it mixes with digestive juices from the liver and pancreas. Bile from the liver breaks up fat. Pancreatic juice neutralizes stomach acid and contains enzymes that digest carbohydrates, proteins, and fats.
