Detailed explanation-1: -Somatic Cells In humans, somatic cells are diploid, meaning they contain two sets of chromosomes, one inherited from each parent. DNA mutations in somatic cells can affect an individual, but they cannot be passed on to their offspring.
Detailed explanation-2: -Later, as biochemical analysis became possible, chromosomes were found to consist of both DNA and protein. We now know that the DNA carries the hereditary information of the cell (Figure 4-2).
Detailed explanation-3: -The first cell of a new human being forms during fertilization when an egg cell (from the mother) combines with a sperm cell (from the father). This cell has the genetic information that includes the encoded building instructions for the whole body.
