Phylogenetic tree transcript - [Voiceover] The amino acid sequence of cytochrome c was determined for five different species of vertebrates. The table below shows the number of differences in the sequences between each pair of species.

So, just to give us some context phylogenetic /uk-writing-tips.html what we're talking about. We're talking about cytochrome c. This is a protein. You might remember it when we studied the electron transport chain.

You don't really have to know that for this biology essay, but it's a protein that's found in a lot of different species, and we're going to compare the difference biology essay the sequence of amino acids for phylogenetic tree protein in the /essay-on-black-racism-in-american.html species.

So even though you have the same or similar protein, link call biology all cytochrome c, the sequence might be slightly different when you go from one species of vertebrate ap biology essay phylogenetic tree another.

And the way to read this is for each of these rows you could say, all right, this row describes D. There's clearly going to be zero differences essay phylogenetic tree that species and itself.

ap biology essay phylogenetic tree All right, phylogenetic tree let's answer their question. Using the data in the table, create a homework site ut tree on the template provided to reflect the evolutionary relationships of the organisms. Provide reasoning for the placement on the tree of the species that is least related ap biology essay phylogenetic tree the others.

So, looking at these differences, it's reasonable ap biology essay phylogenetic tree say, well, the things that have the fewest differences in the sequence of cytochrome c, well, those are probably most closely related.

And they already gave us a tree here, so whatever goes here and here are probably pretty closely related. They shouldn't have too many differences in the sequence of cytochrome c.

And these two should be pretty similar. Shouldn't have many differences. While this one should have a good number of differences from any of the other four. Continue reading let's first look at which ones have very little difference. And I'm just scanning this chart here and looking for small numbers. So click here see here, there's only one amino acid difference, or one sequence.

Well, yeah, one amino acid phylogenetic tree between cytochrome c biology E. So I would say that these are fairly closely biology essay. They phylogenetic tree share an ancestor not too far in the phylogenetic tree past. So let me write E.
