Question

what makes it possible for scientists to splice genes from one kind of living thing with the genes from a different kind of living thing?

Answer 1

DNA is amazingly simple from one species, or even one kingdom to another. There are thousands of genes that are the same. Sometimes the differences in genes of different species is very small, but produces dramatic differences.

The ability to splice genes between species is not universal. You can't, for example, splice the gene that makes long legs great for running fast from a gazelle to a fish. The egg would die. But sometimes the gene's action will work the same in both species. One successful example of this is when scientists took a gene from a glowing fish to make mice glow. The action in the cells of the mice was similar enough to their normal functioning that it worked just fine.

But you asked why. Genes are codes for cells to make proteins. If the gene can be spliced into the DNA, and if all other factors in the cell support the creation of that protein, and if the body (other cells) know how to use that protein, then the splicing will be effective.

Answer 2

They use restriction endonucleases that understand a particular sequence on the DNA it truly is elementary to both organisms, and is placed in a noncoding area (so major genes are literally not reduce up) Then, they take the gene that they reduce out and combine it with the reduce DNA of even with they opt for to insert the gene into, and upload DNA ligase. The gene will connect and become component to the DNA.

Answer 3

All genes are made from the same 4 bases.

Answer 4

I'm guessing splice means combine, but I don't think scientists are even able to do this. If they can, then I'm guessing you won't find the answer since it is a very complicated process.
