1. The discovery has opened new avenues for research and potential treatments for various diseases.2. The ethical implications and potential risks of such technologies, notwithstanding their benefits, need careful consideration.3. Advances in genetic engineering, such as CRISPR-Cas9, have enabled precise manipulation of DNA sequences.4. Scientists can now potentially correct genetic mutations, prevent hereditary conditions, and even engineer more resilient crops.

In the study of molecular biology, scientists have discovered that cells communicate with each other through a complex process known as signal transduction, which involves a series of steps where information is passed from a receptor to a series of proteins inside the cell. ______ scientists found that disruptions in this process can lead to diseases such as cancer.24Mark for ReviewABCWhich choice completes the text with the most logical transition?AIn addition,BHowever,CSimilarly,DAs a result,

Five jumbled up sentences (labelled 1, 2, 3, 4 and 5), related to a topic, are given below. Four of them can be put together to form a coherent paragraph. Identify the odd sentence and key in the number of that sentence as your answer.1. Among these innovations, gene editing techniques like CRISPR-Cas9 have revolutionized the way we can manipulate genetic material, offering new possibilities in medicine.2. Biotechnology has also paved the way for the development of biofuels, which are seen as a sustainable alternative to fossil fuels and help in reducing carbon emissions.3. The field of biotechnology has seen remarkable advancements in recent years, with breakthroughs in genetic engineering and molecular biology.4. However, the ethical implications of cloning have sparked significant debate, particularly concerning the cloning of entire organisms.5. These advancements include personalized medicine, where treatments are tailored to an individual's genetic makeup, enhancing the effectiveness of therapies.

15)Some members of the scientific community urge caution around the use of genetically modified (GM) crops, arguing that the long-term health effects of consuming such crops are unknown. ______ they are concerned about the environmental risks associated with GM crops, including their potential to disrupt natural ecosystems by displacing or cross-pollinating with wild plants. Which choice completes the text with the most logical transition?STRPRAEN-015Additionally,For instance,Nevertheless,On the contrary,

Recent technologies, such as genetic manipulation, are again opening the door for a resurgence in eugenic (planned breeding) practices, but we would be wise to remember the fact that humans now being able to alter people's genetic code tells us nothing about what we should do with that information. Although new technological opportunities offer us possibilities to improve many people's lives, our recent past illustrates the inherent dangers in using science to justify our actions.11Mark for ReviewABCWhich choice best states the main idea of the text?AApplication of newly discovered principles of genetics poses a risk due to their unintentional outcomes.BThe field of eugenics has supplied us with new insights but its practical utilization remains to be seen.CWhile applying any new principle with the aid of technology, there are consequences along with the benefits.DIt is important to tread cautiously in experimentation of planned breeding as it is a double-edged sword.
