I believe the answer is within 30 minutes after exercise.
There are two optimal windows of recovery following a hard workout that play crucial roles in helping the body recover as quickly as possible. The first window of recovery begins within 30 minutes following prolonged exercise. The second window for optimal recovery is from one hour to three hours post workout.
Transposable elements are considered to be responsible for vast range of genome diversity and gene silencing.
Explanation:
Transposable elements are short sequences of DNA that have the ability to move from one location to another in the genome. During this process they copy themselves.
The entire process carried out by transposable elements to copy themselves and move from one location to another is called transposition.
Transposition may result in mutation and is potentially a major source of genome diversity and change. If a transposon inserts itself into the coding region of a gene,it interrupts the coding sequence and inactivates the gene expression.
In addition to this, a transposable element may contain transcription or translation termination signal that will block the gene expression downstream of insertion site.
The answer would be the chloroplast. The cell wall mainly covers and protects the cell's insides.
