The distance between genes on the gene map is measured in mi

The distance between genes on the gene map is measured in minutes because the distance between genes is measured by the time it takes for the gene to be transferred from the host cell into the recipient cell. This distance can be determined by looking at the first appearance of each phenotype on the graph. What is the distance between the met and his genes? What is the distance between the met and his genes?

a) less than 1 minute

b) approximately 1 minute

c) between 1 and 2 minutes

d) between 2 and 3 minutes

35 20 15 10 12 14 16 Time (minutes) met his pro bio

Solution

b) approximately 1 minute

The time taken for the transfer is approximately one minutes since transfer of met started after 8th min and transfer of his started at 10th min.
