What does the process of differential centrifugation achieve?
What does the process of differential centrifugation achieve?
If a toxin, such as a bacterial toxin, destroys ribosomes, what cellular activity will be affected first?
protein synthesis
Why is it advantageous for cells to be small
A small cell has a small volume relative to surface area, thereby increasing efficient transport.
How does the scanning electron microscope differ from the transmission electron microscope?
The SEM gives a three dimensional image of the object being studied
Evidence that all living cells have a common origin is best illustrated by the:
basic similarities in cell structure and chemistry
DNA is associated with RNA and certain proteins, forming a complex called:
chromatin
What is one cellular characteristic found in all prokaryotic and eukaryotic cells?
plasma membrane
