The general expression for mutation rate is the number of mutant cells over the total number of mutant cells. Given that the cells were treated and then allowed to complete one round of replication, the final computation of mutation rate should be divided by two (two cells are plated for each cell treated). What is the rate of mutation at the locus associated with leucine biosynthesis

The rate of mutation is low

Explanation:

Biosynthesis of leucine means the biological production or breakdown of leucine.

Leucine is very important in the body because it helps in the protein synthesis and muscular development. It should be understood also that too much of leucine in the body might result to low blood pressure.

In this case, the rate of mutation to the locus related to leucine biosythesis will be low.

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.
