7. You wish to determine the sequence of a short peptide. Cleavage with trypsin yields three smaller peptides with the sequences: Leu-Glu, Gly-Tyr-Asn-Arg, and Gln-Ala-Phe-Val-Lys. Cleavage with chymotrypsin yields three peptides with the sequences: Gln-Ala-Phe, Asn-Arg-Leu-Glu, and Val-Lys-Gly-Tyr. What is the sequence of the intact peptide

How does the fossil record provide evidence that the modern whale evolved from the anthracotheres? a) the modern whale looks like their ancestor the anthracotheres. b) the modern whale has all of the same structures as their ancestor. c) there is not enough evidence to suggest the the modern whale evolved from the anthracotheres. d) the anthracotheres has a structure that is still present in the modern whale, but is no longer of use to the modern whale.
