WebThis cell is in interphase (late G _2 2 phase) and has already copied its DNA, so the chromosomes in the nucleus each consist of two connected copies, called sister chromatids. You can’t see the chromosomes very clearly at this point, because they are still in their long, stringy, decondensed form. WebSomatic refers to the cells of the body that are in contrast to the germline or reproductive cells. These somatic cells are diploid in nature. They are responsible for the growth and development of an organism. What are some examples of somatic cells? Somatic cells make up the connective tissue, skin, blood, bones and internal organs.
