I will try to recall the question... The idea is
What is genetic element with several genes, able to catalyze its own movement between
chromosomes, has inverted 35- nucleotide repeats and incapable of replicating independently
A. complex transposon
B. insertion sequence
C. plasmid
D. regulon
May be there were more choices, not sure... A or C?

Hello? Does anybody knows genetics? Come on people... Genetic mobile elements...
It is not D. because Regulon- collection of genes under regulation by the same regulatory protein...It is not moving anywhere.
It is nt B. because Insertion sequence does not have several genes, just one which codes for transposase, which will move it...
Everybody agree?
On real test I picked up A. but now I think may be it is C.
Anybody?

answer choice is A, i was wrong, my genetic knowledge is very poor, can you explain why its A? and also why you didnt pick C? thanks.

- All you really need is the first line; gene capable of catalyzing its own movements within and between chromosomes... Transposon!!!
- many genes - transposon ;single gene - insertion sequence
First 2 points taken from above links, so, can plasmid replicate independently?

Plasmid will replicate in bacteria, so it is not independent...
Thanks antidepressant!
