4. A living cell is not a simple geometric shape, like a sphere or a cube. What sort of weird cell shape might increase the rati
Gnesinka [82]

Answer:

Gabriel's horn

Explanation:

What the question is asking for is a 3-dimensional shape that has a lot of surface area and only a little volume. The first thing I thought of was a geometric figure called Gabriel's Horn. A quick search on Wikipedia will explain better than I can, but basically it has infinite surface area but finite volume. You probably couldn't test the shape in any experiment, though, since it's only theoretical and can't exist in real life.

Let me know if I can explain anything in a clearer way!

Explain how a change in the amino acid sequence of the FXR1 protein could decrease the ability of the protein to bind to RNA
Likurg_2 [28]

The amount of proteins which is forming the SDS-resistant aggregates is isolated and purified by using the PSIA-LC-MALDI proteomic approach9 specially made for brain tissues.

Explanation:

  • It is known as a regulatory mechanism through which the variations in the incorporation of the exons into mRNA gives  the production of more output which is to related protein, thus results in expanding possible genomic outputs.
  • Amyloids are the β-sheets-rich protein fibrils which can cause neurodegenerative and other incurable human diseases trapping  millions of humans across the world.
  • RNA molecules which are colocalized with FXR1 in cortical neurons are insensitive to the treatment with RNase A.
  • FXR1 also colocalizes in cortical neurons using the amyloid-specific dyes
  • FXR1 is also known to make different forms of RNA molecules and affects their stability and translation efficiency17.
  • To determine the binding energy  of FXR1 with mRNA, the brain cryosections were hybridized with biotinylated poly-dT.
