The sketch below that looks like an X represents a replicated chromosome that has two sister chromatids. Think carefully, now. Third, the head of a sperm cell is almost all nucleus. Even still, mutations within the DNA are a fairly common event. The DNA molecules produced through the cloning techniques are used for many purposes which include: DNA cloning can be used to make proteins such as insulin with biomedical techniques. During Interphase, the DNA is copied. DNA is found in the nucleus of a cell (nuclear DNA) and in mitochondria (mitochondrial DNA).It has two nucleotide strands which consist of its phosphate group, five-carbon sugar (the stable 2-deoxyribose), and four nitrogen-containing nucleobases: adenine, thymine, cytosine, and guanine.. During transcription, RNA, a single-stranded, linear molecule, is formed. Because DNA can be damaged in many ways, the process of DNA repair is an important way in which the body protects itself from disease. the sugar and phosphate molecules forming the vertical side pieces of the ladder.
