Translation: What type of bond holds amino acids together? (NOTE that this is the bond formed during translation) peptide bonds Translation: In a tRNA molecule, where would you find the anticodon loop? 3' end of tRNA and cognate amino acid brought together by aminoacyl-tRNA synthetase enzymes (runs 5' to 3') Translation: What is the anticodon complementary to (what does it recognize)? a corresponding codon in a messenger RNA (mRNA) sequence Translation: What specific type of secon...

Pathophysiology Review for Exam 1 1. Know the differences between prokaryotes and eukaryotes a. Prokaryotes – i. Bacteria and Archaea ii. no nucleus (single, circular chromosome) iii. genes not surrounded by a membrane iv. cell walls composed of a polysaccharide called peptidoglycan, though some bacteria lack cell walls v. smaller than eukaryotes vi. Lack histones (they coil stuff) vii. live singly, in pairs, chains, or clusters viii. enjoy moist environments like Yellowstone Natio...

Why is myelin important in the nervous system? A. It allows signals to travel faster along axons because depolarization occurs only at myelinated locations. B. It allows signals to travel faster along axons because depolarization occurs only at nonmyelinated locations. C. It bundles the dendrites of adjacent neurons together. D. It increases capacitance across the cell membrane, which helps electrical signals to leave the axons. E. It traps neurotransmitters, increasing their concentratio...

WGU Biochemistry Final Review 1. The polymerase chain reaction is a tool used to study protein structure. True False False Feedback PCR is a tool used to amplify a specific segment of DNA. What color is the primer in the following diagram? Red Purple Blue Red Feedback Recall from the section on DNA replication that DNA polymerase needs a primer to begin DNA synthesis. This requirement means the primers will direct the DNA polymerase to only synthesize complementary stran...
