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.

You have found a new prokaryote. What line of evidence would support your hypothesis that the organism is a cyanobacterium? You

ella [17]

Answer:

It is able to produce oxygen

Explanation:

The line of evidence that would support my claim is that the observed prokaryotes can produce oxygen. The cyanobacteria or the blue green algae are the only know prokaryotes that utilises photosynthesis which leads to the release of oxygen. Since it has already been established the discovered organisms is a prokaryote, it can then be confirmed that since this organism can produce oxygen, it is a cyanobacteria and that it also has features peculiar to the cyanobacteria
