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:

Dangers of genome editing in humans:

Thus, human gene editing is a controversial issue.

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 element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.

explanation:

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
