Explanation:
Options are no given in the question. The complete question is as follows:
If autophosphorylation of CheA protein does not occur, then Escherichia coli cells must be_________________.
A. in a gradient of a chemoattractant.
B. in a gradient of a chemorepellant.
C. tumbling.
D. rotating flagella clockwise.
Answer:
A. in a gradient of a chemoattractant
Explanation:
The autophosphorylation of CheA is described as the autophosphorylation of histidine kinase (s) (CheA protein) in the presence of MgCl 2 and ATP.
If autophosphorylation of CheA protein does not occur in Escherichia coli, then the cells of E.Coli undergo methylation events that allow cell in a gradient of chemoattractants which increases the activity of CheA and CheY-P and cells adapt according to the concentration of chemoattractant.
Hence, the correct answer is A.
