When infected with viruses, bacteria capture small pieces of the viruses' DNA and insert them into their own DNA in a particular pattern to create segments known as CRISPR arrays. If the viruses attack again, the bacteria produce RNA segments from the CRISPR arrays that recognize and attach to specific regions of the viruses' DNA. The bacteria then use Cas9 or a similar enzyme to cut the DNA apart, which disables the virus. + sign character (+) followed by a four digit time providing hours and minutes of the offset.

An impaired driver left three families without power as temperatures are expected to drastically drop after he hit a duplex with his car.

Genome editing is of great interest in the prevention and treatment of human diseases. Currently, genome editing is used in cells and animal models in research labs to understand diseases. Scientists are still working to determine whether this approach is safe and effective for use in people. It is being explored in research and clinical trials for a wide variety of diseases, including single-gene disorders such as cystic fibrosis, hemophilia, and sickle cell disease. It also holds promise for the treatment and prevention of more complex diseases, such as cancer, heart disease, mental illness, and human immunodeficiency virus infection. CRISPR-Cas9 was adapted from a naturally occurring genome editing system that bacteria use as an immune defense.

Ethical concerns arise when genome editing, using technologies such as CRISPR-Cas9, is used to alter human genomes. Most of the changes introduced with genome editing are limited to somatic cells, which are cells other than egg and sperm cells . These changes are isolated to only certain tissues and are not passed from one generation to the next.

The 2022 holiday season is just around the corner and local businesses and organizations are gearing up for drives and events to celebrate. City Manager Stephen Wade said the plan needs to be settled sooner than later, citing the 2023 end date for the current structure and needing time for budget planning that would be affected by the new rates. The cold weather is on its way and the Topeka Rescue Mission and other organizations are planning to keep people on the street warm. Our curators include experts in a wide variety of anthropological topics, from human evolution to cell phones.

However, changes made to genes in egg or sperm cells or to the genes of an embryo could be passed to future generations. Germline cell and embryo genome editing bring up a number of ethical challenges, including whether it would be permissible to use this technology to enhance normal human traits . Based on concerns about ethics and safety, germline cell and embryo genome editing are currently illegal in the United States and many other countries.

The purpose of the study was to determine the density and pattern of growth of white shrimp of the village Nipah waters. Rain, sleet, snow or 20 below, Kansas weather has a mind of its own and the Topeka Zoo has announced modified hours to prepare. At an early morning meeting, the City of Topeka says it is working with numerous community partners to prepare for this week’s dangerous temperatures.

They create a small piece of RNA with a short "guide" sequence that attaches to a specific target sequence in a cell's DNA, much like the RNA segments bacteria produce from the CRISPR array. When introduced into cells, the guide RNA recognizes the intended DNA sequence, and the Cas9 enzyme cuts the DNA at the targeted location, mirroring the process in bacteria. Although Cas9 is the enzyme that is used most often, other enzymes can also be used.
