Question
The myoglobin from two different mammalian organisms would be expected to a. Have high sequence homology but no identities (identity = exactly the same amino acid in the same position of the sequence) b. Have low sequence homology c. Have only conservative replacements d. Have high homology and some sequences identities In aminoacyl-tRNA molecules, the amino acid covalently attached to a ribose through a. The amine group b. The carboxyl groups c. The alpha-carbon d. None of the above Trypsin or carboxypeptidase digestion of a 101-amino acid protein, in two separate experiments, yielded two identical 99 amino acid peptides (among a collection of other products not considered here). This means that a. The protein is likely to contain a lysine residue as the N-terminal amino acid b. The protein is likely to contain a lysine as its C-terminal ammo acid c. The protein does not contain lysine or arginine d. The protein likely to contains arginine as amino acid number 99 e. The protein is likely to contain arginine as a amino acid number 3. The requirement for GTTP in protein synthesis is associated with the a. Energy coupling for the petidyltransferase catalytic step b. Ribosome assembly c. Formation of aminoacyl tRNAs d. Binding of the codon to the anticodon The molecule above is an intermediate in a reaction catalyzed by a DNA polymerase b RNA polymerase c. A synthetase d An isomerase e A phosphorylaseExplanation / Answer
Answer 32: d
