Summary Introduction
To review:
The given blank space in the statement, “A property conferred by the complexity and dynamics of a system is called an ______________ property.”
Introduction:
The complex and varying biochemical reaction pathways can be described on the basis of two concepts: emergence and robustness. Biologists dealing with systems biology have divided complex organisms as systems, networks, modules, and motifs.

The carbon-nitrogen peptide bond is rigid, but rotation can take place
about the bond between the nitrogen and a-carbon atoms and the bond
between the a-carbon and the carbonyl carbon atom. These bond angles
define the conformation of the peptide chain.

Please give an intuitive explanation of the difference, if any, between toxicokinetics and pharmacokinetics.
A protein biochemist attempted to determine the amino acid sequence of a decapeptide. The results from the trypsin,
chymotrypsin, and cyanogen bromide treatments are shown:
⚫ Trypsin digestion gave two fragments with multiple residues (not in order):
• T1: Ala, Arg, Phe, Gly, Thr, Trp, Tyr
o T2: Lys, Met, Val
Chymotrypsin digestion gave four fragments with multiple residues (not in order):
• CT1: Ala, Phe
• CT2: Thr, Trp
• CT3: Lys, Met, Tyr, Val
。 CT4: Arg, Gly
⚫ Treatment with cyanogen bromide yielded a single amino acid, methionine, and a nonapeptide.
What is a possible sequence of the decapeptide? Use three-letter abbreviations in your answer, and add a dash between
each residue.

Why do these amino acids with the same number and kinds of atoms have different helix-forming tendencies? L-isoleucine's methyl group sterically interferes with α-helix formation, whereas L-leucine's methyl group does not interfere. L-isoleucine lacks an NH group that can donate a hydrogen bond to stabilize an a helix, whereas L-leucine has an NH group. L-isoleucine contains a hydrogen-bond acceptor in close proximity to the main chain, whereas L-leucine lacks this group. L-isoleucine's ring structure prevents it from assuming the op value to fit into an a helix, whereas L-isoleucine does not have a ring structure.arrow_forwardSamples of the octapeptide AVGWRVKS are subjected to proteolytic cleavage by either trypsin or chymotrypsin.

These cells were then transferred to a medium with the "light" isotope of nitrogen, 14N. The results of the experiment supported the hypothesis of semiconservative replication, which was proposed by Watson and Crick. Heavy DNA (15N DNA), hybrid DNA, and light DNA (14N DNA) can be separated by centrifugation. If cells containing 15N DNA are transferred to a medium with only 14NH4Cl as a nitrogen source, what percentage of daughter molecules are composed of hybrid DNA after 3 generations? daughter molecules composed of hybrid DNA: Predict what percentage of daughter molecules would be composed of hybrid DNA if DNA exhibited conservative replication (i.e., if a daughter DNA molecule were composed of only newly synthesized DNA). daughter molecules composed of hybrid DNA: % %arrow_forward

Assume that SDS-PAGE is performed under reducing conditions. Proteins are visualized using a dye that binds to the gel matrix, but not to proteins. Protein-SDS complexes have similar mass to charge ratios; therefore, separation is by size. Proteins are separated in a polyacrylamide gel matrix. Protein-SDS complexes migrate toward the negative electrode. Smaller proteins migrate faster through the polyacrylamide gel. Sodium dodecyl sulfate binds proteins, resulting in SDS-protein complexes that are similar in size.arrow_forwardClassify each feature as charactistic of DNA polymerase or RNA polymerase.
