in most environments, the nutrient concentrations outside the cell are lower than inside the cell. how can a microbial cell obtain nutrients if the concentration gradient is NOT favorable?
a. through active, ATP-dependent transportb. using facilitated diffusionc. swim and tumbled. by forming biofilmse. none of the above
What does this show about the relation between voluntary and involuntary reflex movement. If the bacteriorhodopsin molecules were randomly oriented, would you expect ATP to be synthesized? Give details about the answers.
How do protists transport wastes and ions.
Codons with U or C as the second nucleotide, for example, tend to specify hydrophobic amino acids. Can you recommend a possible explanation for this phenomenon in terms of the early evolution of the protein synthesis machinery?
What would happen if the I gene was moved to a different location in the genome? What would happen if the lac promoter was moved to a different location?
What effect might this have on cell lineages during development. Describe the physical changes that would occur in SIM medium if you inoculated an organism that was negative for hydrogen sulfide but positive for indole production and motility.
In what ways are we similar to primitive single celled organisms such as bacteria? What does this suggest in terms of our evolution?
You have a cell suspension containing 4 * 10^5 cells/ml and want to seed these cells on microcarriers at a density of 1* 10^4 cells/cm^2. The average diameter of the microcarriers is 157.5um (the diameter range supplied by the vendor is 115-200um)..
Cells have several mechanisms to prevent the production and accumulation of truncated protein fragments. To illustrate why these fragments can be deleterious, consider a transcriptional activator protein called Groovy that binds to an enhancer ele..
What causes pH to increase or decrease with E. coli cells when they are in a sample of pond water and they are either left in the dark or in the light for a week undisturbed?
A 2500 base-pair long cDNA of unknown sequence was cloned into the MCS of a plasmid vector that has universal priming sequences adjacent to and on both sides of the MCS.
Which chemical modification do we associate with changing the activity of an enzyme in a transient/non-permanent manner?
In 2004, 45% of the corn, 85% of the soybeans, and 76% of the cotton grown in the United States was from genetically modified (GM) seeds.
