What is the likely fate of a piece of DNA transferred into an alien organism?
Options
- Awill multiply in the progeny cells of the organism
- BIt will become a part of the chromosome and replicate
- CIt will not be able to replicate
- DIt will not be able to multiply
Correct answer
B. It will become a part of the chromosome and replicate
Step-by-step solution
Do you know the likely fate of a piece of DNA, which is somehow transferred into an alien organism? Most likely, this piece of DNA would not be able to multiply itself in the progeny cells of the organism. But, when it gets integrated into the genome of the recipient, it may multiply and be inherited along with the host DNA. This is because the alien piece of DNA has become part of a chromosome, which has the ability to replicate. In a chromosome there is a specific DNA sequence called the origin of replication, which is responsible for initiating replication..
