No, retrotransposons and retroposons are not the same.
Retrotransposons act like retrovirus RNA with the exception of their being unable to escape and infect other cells. Retrotransposons begin as an RNA sequence and encode for a reverse transcription to make them into a double stranded DNA fragment which can then be inserted into other sections of the genome.
Retroposons are repetitive DNA fragments that have already been inserted into the genome. The difference is that the DNA has been reverse transcribed from any RNA molecule.
In contrast to retrotransposons, the retroposons never encode reverse transcriptase. Which means they are not capable of autonomous transposition activity, unlike transposons.
A major distinction is that transposons move within the genome via a "cut and paste" mechanism, while retrotransposons use a "copy and paste" mechanism involving reverse transcription of an RNA intermediate. Retrotransposons also contain a reverse transcriptase gene, which transposons lack.
The type of transposon that is an ancient parasitic sequence is called a retrotransposon. Retrotransposons move by being first transcribed into RNA, then reverse transcribed back into DNA before insertion into a new genomic location. This process is similar to the replication of retroviruses like HIV.
does the same organism always react to the same stimulus at the same way
No. It is not the same. the number of valence electrons are same for the elements in the same column (group).
No, elements in the same column are in the same family.
A transposon moves via a DNA intermediate and a retrotransposon via an RNA intermediate.
