Gene Splicing Ryley mcclellan, tyler duderstatt pd. 4/5

Gene Splicing is after transcription where a single gene can code for multiple proteins. Gene Splicing is done in eukaryotes, prior to mRNA translation, by adding or deleting section of pre-mRNA.

Gene Splicing is when a part of DNA is cut out and new DNA is added in its place. Enzymes act as genetic “scissors” to cut out a specific part of the DNA sequence. An enzyme called Ligase the repairs the DNA by putting a new segment of DNA in the old ones place

Gene splicing is important because it provides protein diversity. 40-60% of DNA show splicing. It provides medical benefits and has allowed humans to create healthier versions of food

One of the medical benefits is it can been used to create vaccines where they splice a virus’ DNA and create a harmless bacteria which produces proteins that can be collected and made into a vaccine

Gene splicing has also allow scientists to create a better version of rice that contains vitamin A. This rice has helped people in poorer countries remain healthier.

One draw back is Gene Splicing can lead to many different types of heredity diseases. Research is still detecting other problems as well.

So ethical considerations arise from this technological advancement including the question "Should we change someones DNA?" or "Should we be able to pick and choose genes?"
