Let's call the colour alleles C for dominant purple, and c for recessive white.

We have crossed Cc with Cc.  So if we put that in a Punnett square, we'd have a CC, two Cc and a cc.  That would give us a 3:1 ratio of purple to white, so you'd expect 15 purple and 5 white flowers. :)

In a cell with defective chaperones, Question 14 options: proteins would not be able to exit the ribosome. the concentration of
BartSMP [9]

Answer:

the concentration of misfolded proteins would be higher than normal.  

Explanation:

Chaperones proteins are required for the correct protein folding of proteins. These proteins were first discovered in bacteria. The level of chaperones is increased under thermic stress conditions, it is for that reason that they are also known as heat shock proteins (Hsp). For example, Hsp70 is a chaperon protein constitutively expressed under stress conditions that is involved in the folding of protein precursors and the refolding of misfolded proteins. In humans, Hsp70 is encoded by the HSPA1A gene, and its increased expression level is related to different health problems including neurodegenerative diseases, cerebral ischemia and epilepsy.
