The Lederberg experiment that used the technique of replica plating showed that mutations are random and are not a result of the needs of the organism.

<h3 /><h3>What is a random mutation?</h3>

Random mutations are just that, they are changes in the genome of an organism that arise randomly. These mutations are the backbone of evolution and natural selection in that when they arise, if the organism becomes more adapted to survival as a result of this mutation, it increases its odds of survival through natural selection.

Therefore, we can confirm that The Lederberg experiment that used the technique of replica plating showed that mutations are random and are not a result of the needs of the organism.

amm1812

Answer:

The correct answer is - Inhibits cell cycle progression.

Explanation:

Smoking marijuana affects the body in several ways and also causes mutation to the DNA which leads to the disruption of the cell cycle. The major effect on the cell cycle of marijuana is due to the chemical present in it known as #9 -Tetrahydrocannabinol.

THC or #9  -Tetrahydrocannabinol inhibits the cell cycle progression by arresting the cell cycle in different stages that prevent the cell to proliferate and it is proposed for the research in treating tumors.
