Is a peptide bond polar/unpolarpolar does cis or trans dominate for the configuration of a peptide bondtrans is favored by 1000 fold because the cis formation has steric hinderance What are the three bonds in a peptide chainN-Calpha Calpha-C C-N how long is a peptide bond1.32A What is the angle between Calpha-N calledphi what is the angle between Calpha-C calledpsi

Life characterized byComplexity Metabolism (use of energy) Sense and Respond to stimuli Self-replication with enough change for evolution bacterial cells store DNA innucleoid Eukaryotic cells defined bynucleus (some become anuclear) membrane-enclosed organelles (mitocondria, chloroplasts, lysosomes) spatial separation of energy-yielding & consuming reactions --> maintain homeostasis and stay AWAY from equilibrium

1. The most precise modern definition of a gene is a segment of genetic material that: A) codes for one polypeptide. B) codes for one polypeptide or RNA product. C) determines one phenotype. D) determines one trait. E) that codes for one protein. B
