Genome editing is a group of technologies that enables scientists to edit an organism's DNA. One genetic editing technology is called CRISPR-Cas9, which was developed based on a naturally occurring genome editing system in bacteria. CRISPR-Cas9 uses a cell's own machinery to edit the genetic material; scientists can add or remove genetic sequences from an organism's genome. CRISPR-Cas9 can customize an organism's DNA by replacing an existing segment with a customized sequence of DNA. In 2018, a Chinese scientist announced that he had created the world's first genome-edited babies, twin girls born in November 2018. The scientist wanted to create children who were resistant to Human Immunodeficiency Virus (HIV). The Chinese scientist used CRISPR-Cas9 to disable a gene called CCR5, which encodes a protein that enables HIV to infect cells. This announcement caused outrage in the international scientific community. While genomic editing of bacteria and viruses is commonly used in science, genetic editing of humans remains highly controversial. Why do you think the news of this new use of CRISPR-Cas9 in humans generated so much anger in the research community and in the world at large? What are the dangers of genomic editing in humans?

Gene editing is a technique that is used in research areas to modify genes of organisms for improving their function and to treat diseases.

Genome editing generated anger when used on Humans because:

Genome editing or any research based on humans as a subject is considered very controversial and have always created anger even in the case of clinical trials.Genome editing has been conducted on animals for years and the results and side effects are the reasons that the human specimens cannot be used for experimentation.

Dangers of genome editing in humans:

The accuracy rate of gene editing is still not 100% and they are chances that unintended changes can occur during editing.These mistakes and errors can affect the human as a whole and will ruin its whole life.The possibility of getting cancers and getting vulnerable to biological attacks makes gene editing in humans a disadvantage.

Thus, human gene editing is a controversial issue.

Answer from: elijah1090

Explanation:

It generated anger because:

1) Human gene editing is highly controversial as humans are considered the "top" organisms and any tests conducted on humans whether it be clinical trials of medicine and such need to be approved and need to be ethical.

2) We are still years behind in terms of knowledge of genomic editing on animals and its side effects, and taking this in account, performing such editing with humans is obviously going to draw controversy as we do not know enough about genomic editing.

Dangers of editing in humans:

1) Although Crispr-Cas9 is highly accurate, it is still capable of making mistakes and we are still unsure about how those mistakes can affect the whole human. After all, the editing needs to be done in embryo for it to make a pronounced effect later in life on the grown human so any mistakes could ruin the new life of this human.

The construction of phylogenetic trees is a mapping out the proposed divisions and common ancestors of all living species. traditionally, these trees have been built using morphological data, such as appearance and embryology. recently, it has been possible to construct these trees using molecular data. phylogenetic trees based on different types of information agree with each: that there is strong evidence of a real underlying common descent. this phylogenic tree is composed based on molecular data (rrna). what statements can we infer are true about the organisms throughout the tree? because the tree is rooted, all branches share a common ancestor. all organisms have some sort of cellular structure/organization. all eukaryotes evolved from bacteria. since the organisms contain rna, they share the same dna. if the organisms contain rna, the share the same four nitrogen bases.

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.

The ancestors of plants that lived in water had plenty of water for the young. angiosperms are a group of land plants that evolved a reproductive trait for living on land. this trait protect young plants by allowing them to grow only when water is present and the conditions for healthy development are right. what trait most likely young angiosperms in this way?

Juan and carol were studying invertebrates in biology. they knew that segmented or earth worms preferred a dark, moist habitat. during this lab, they would be investigating the responses of organisms called planaria or dugesia tigrina. these were simple flatworms that still had a one-way digestive system and a very simple nervous system. juan and carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. they shined a light on the dish. next, they removed the paper and placed a small amount of chicken liver at one end of the dish. they added a few large salt crystals to the water. finally, they added drops of hot water to the cool water in the petri dish. their results can be seen in the data table. according to their experiment, all but one conclusion is valid.
