Question

Based on the tree of life in Figure 16.12, would you expect human proteins to be more similar to fungal proteins or to plant proteins? Would you expect plant proteins to be more similar to fungal proteins or to human proteins?

Accepted Answer

Hello everyone and welcome to today's video. So why do plant proteins generally resemble fungal proteins more than animal proteins. As answer choice A we have plants and animals share a more recent common ancestor. As answer choice B we have plants and fungi share a more recent common ancestor as answer choice C we have animals and fungi share a more recent common ancestor. And as answer choice D we have fungal proteins are structurally similar to plant proteins. Well, remember that these proteins are going to be coming from M R N A or juice or juice R N A that is going to be coming from the N N A. So if we have plant proteins being very similar to fungal proteins, this is because the gene sequences that code for plant and fungal proteins are very similar. Now, remember the process of evolution, all animals have a, all animals, plants and fungi have a certain common ancestor. So the more recent this common ancestry is to certain groups, the more similar their DNA is going to be as it has not evolved as much as it turns out, plants share a very recent common ancestor with fungi, meaning that the DNA is very similar. Now, in, in the sense of animals, animals share a more far apart common ancestor with plants are in fungi. So their proteins are not as similar. Their for answer choice. B plants and fungi share a more recent common ancestor is going to be the correct answer for this question. I really hope this helped you and I hope to see you on the next one.
