Question

What is CODIS? Describe the four most important features of genetic markers used in this system.

Accepted Answer

Welcome back, everyone. Here's the next problem. It is a program developed by the FBI to store and analyze DNA profiles for forensic purposes. Choice A CODIS, which is C O D I S Choice B Blast. Choice C PC R or Choice the Eliza, all of these being acronyms for various things. So in all capital letters, so the program that stores DNA profiles for forensic purposes is choice A CODIS. We can look at our other answer choices to see why they're not correct. Uh Choice B Blast is a database that allows comparisons between DNA and protein sequences. So we can search and look for alignment of a gene sequence compared to a protein. It might code for two proteins to each other two DNA sequences to each other, et cetera, but not what we're looking for. So we can cross out choice B to C PC R. Hopefully that's familiar as a method for amplifying a specific DNA segment. So not our answer choice here. And then finally choice D Eliza. And that's a method of asking using labeled antibodies. You can look at large amounts of samples looking for very specific things since the antibodies are very specific to bind to things and just a very useful uh essay technique, very sensitive but not what we're looking for. So we'll eliminate choice B so again, the program that's used to store and analyze DNA profiles for forensic effects would be Choice A CODIS see you in the next video.
