Answer to relevant QuestionsCells of Escherichia coli take up lactose via lac permease, glucose via the phosphotransferase system, and maltose via an ABC- type transporter. For each of these sugars describe: (1) the components of the transport system ...Why are amino acids so named? Write a general structure for an amino acid. What is the importance of the R group to final protein structure? Why does the amino acid cysteine have special significance for protein structure? A structure commonly seen in circular DNA during replication is the theta structure. Draw a diagram of the replication process and show how a theta structure could arise. Describe a habitat where you would find a psychrophile, and one where you would find a hyperthermophile. How can these organisms survive under such harsh conditions? How do cells of Escherichia coli that carry a mutation in mreB ( the gene encoding the protein MreB) look different microscopically from wild- type ( unmutated) cells? What is the reason for this?
