A labaratory investigator want to make a study on cancerogenesis . He injected X in the cell and after this he noticed increased in DNA in the cell. When he injected this “X” in the cell in another site, he found out that this X is activating oncogene and is inhibiting the tumor suppressor genes. Additionally, he noticed that X is capable to replicate by itself. What is this X he injected ?
1.intron
2.exon
3.plasmid
4.transposon

I am between Plasmid and Transposon

I believe the answer is a plasmid. Insertion of a viral promoter has been proven to activate oncogenes.

The methods of oncogene activation are:
1. Amplification
2. Structural mutation in DNA.
3. Translocation from an immunoglobulin.
4. Insertion of viral promoters.

I think it's plasmid as well. Plasmids aren't physically a part of the genome (extra-chromosomal), so that gives them the ability to replicate independently. At least I think so...not 100% sure though.
