7 questions could use some help on for Molecular Biology. Pleasehelp. Just answers will do (I'll figure out), but wouldn't mindexplanations. If answered correctly 5 star guarantee & goodattempt definite 'best answer'. Thanks!
Question1
Which of the following cytoskeletal components is thelargest?
Microtubules
Microfilaments (actin)
Intermediate filaments
Question2
During mitosis, all microtubules emanate from the centrosome.Therefore, the centrosome is an example of:
a microtubule organizing center (MTOC)
A +TIP protein
A catastrophin
A monomer sequestering protein
Question3
Tubulin is a G-protein. It can stabilize microtubules when boundto which of the following?
GDP
GTP
Either GTP or GDP
Neither GTP nor GDP
Question4
In the formation of microtubules, dimers are built when analpha-tubulin protein binds to a beta-tubulin protein. This is anexample of what level of protein structure?
Primary structure
Secondary structure
Tertiary structure
Quartenary structure
Question5
Different tissues in the body express slightly differentversions of alpha tubulin. Which of the following could lead toslightly different alpha-tubulin molecules with a modified proteinsequence?
One tissue has more DNA methylation upstream of thealpha-tubulin gene.
One tissue has more miRNAs produced than the other.
One tissue uses different splice sites than the other.
One tissue has different trans-elements than the other.
Question6
How is confocal microscopy different from traditionalfluorescent microscopy?
The molecules are labelled red instead of green.
The molecules are observed over time.
The molecules are observed in many thin planes, which are thenstacked together to create a crisper image.
The confocal microscope has higher objective power than regularfluorescent microscopes.
Question7
Taxol is a chemotherapy drug that permanently stabilizesmicrotubules and prevents their degradation. Describe howmicrotubules are typically destroyed and why permanentstabilization would kill dividing cells. Note: you may need toreview the basics of cell mitosis from a previous course.
