Acylhomoserine lactones used in quorum sensing regulate their own synthesis by a(n) _________ system. Multiple Choice riboswitch
zmey [24]

Acylhomoserine lactones used in quorum sensing regulate their own synthesis by an autoinduction system.

  • Numerous bacteria use acyl homoserine lactones (acyl-HSLs), significant intercellular signaling molecules, to track the density of their population for quorum-sensing control of gene expression. The LuxI family of proteins produces the signals in question.
  • A lot of proteobacteria use quorum-sensing signals from acyl-homoserine lactones.
  • Cells create a baseline amount of signal at low population densities, and when enough signal has accumulated in the environment, it binds to its receptor and activates quorum-sensing-dependent genes.

In a particular species of frogs, black spots are a dominant trait and their absence is a recessive trait. In a population of fr
swat32

The correct answer is optionD 134/200.

The frequency of the dominant allele can be calculated by the summation of the frequency of the homozygous individual frequency that has  dominant allele  and half of the heterozygous individuals, as half of the heterozygotes have dominant allele.

The frequency is no of individual of desired trait divided by total number of individual.

The calculation is shown below:frequency of dominant allele=frequency of dominant individual+\frac{1}{2} frequency of heterozygotes\\frequency of dominant allele=\frac{50}{100} +\frac{1}{2} (\frac{34}{100} )\\frequency of dominant allele=\frac{50}{100} +\frac{34}{200} \\frequency of dominant allele=\frac{2(50)+34}{200}\\ frequency of dominant allele=\frac{134}{200}
