This session asks, which is The phone was used to determine the function of the system versus Gene. Um so basically, was scientist bird trying to figure out, um, what the function of the cystic fibrosis gene lis if a sickle used by and for medics, which is theat location, Peter Technologies and statistics to basically study general mix biological information. And so basically they were searching for jeans and other organisms that have the same six sequence s the cystic fibrosis gene. And because of the fact Dickie because they knew the function of the gene in other organisms, they could also deduce that function of the cystic fibrosis gene in humans. And so, basically, that was the main procedure in which they used to determine, um basically the function of this gene, which is located right here in this diagram. And they were able to deduce, um, basically what was causing this disease. So if we go down the west, it is not a microwave there. Micro array. They were not using anything any biochemical or molecular biology, biological approaches. They weren't using proteomics. They weren't really studying anything loaded with proteins, but just comparing the sequences of the cystic fibrosis gene to other model organisms on C comparative genomics and by dramatic so that pretty much matches up exactly with what I was describing. So they were comparing the genomes of the cystic fibrosis gene and humans to other jeans with similar sequences in other model organisms to determine the function. And they did not really, they did not seek. What's this gene? It was more about comparing the sequence of genes in relationship with other animals and the function of that gene and other animals that was really the basis for determining the function of the cystic fibrosis gene. So as a result, we could confidently say that sea is the correct answer.
