<span>Stem cells are found in multicellular organism,they are undifferentiated in nature and can form other special cells or could divide in further stem cells by mitosis.The person with brain or spinal cord injury would be interested cause these cells could be used in future to cure the problem.Human embryonic stem cell (HESC) research is ethically and politically controversial because it involves the destruction of human embryos.The resource used was paper by B Lo named 'Ethical Issues in Stem Cell Research'.And according to me research in this field is important for development of mankind</span>
Answer and Explanation:
Interphase is the longest stage of the cell cycle and can be divided into 3 phases: G1 phase, S phase, G2 phase. The newly formed cell matures during the G1 phase. If the cell is going to divide, it enters the S (synthesis) phase where the DNA is replicated and the G2 phase where more growth occurs. The cells undergoing meiosis have only one interphase. After telophase I the cell enters into prophase II without having interphase II.
Answer:
Relation between mutagens and carcinogens. Mutagenicity and carcinogenicity are clearly correlated. One study showed that 157 of 175 known carcinogens (approximately 90 percent) are also mutagens. The somatic mutation theory of cancer holds that these agents cause cancer by inducing the mutation of somatic cells.
Answer:
three risks that are associated with genetically engineered plants?
Three risks involved in genetically engineered plants include;
Resistance
Mutation
Explanation:
Over time plants resist genetically engineered process as a result of exposure to such measure over time which enable such plant to develop resistance over time and pass the traits to their offspring.
