Respuesta :

One reason that RNA was eventually replaced by DNA as the molecule of choice for storing genetic information is that the double helix of DNA is better able to correct errors in replication.

The double helix of DNA replaced RNA as a more stable molecule for storing the increased amounts of genetic information required by such cells, replacing RNA, which is thought to have been a more recent addition as the accumulation of additional protein catalysts allowed for the evolution of more effective and complex cells.

What led DNA to become the dominant genetic material over RNA, then? The RNA world theory states that since DNA is chemically more stable than RNA, it evolved to store genetic information instead of RNA. DNA's double-stranded structure also gives it the ability to rectify replication mistakes.
