DNA replication is much more accurate than RNA transcription. In DNA replication, only one base in every $10$ million $({10}^7)$ to $1$ billion $({10}^9$ average, is inaccurately placed, versus RNA transcription, which results in approximately one base in every $10$ thousand $({10}^4),$ on average, inaccurately placed.

What is the primary reason that transcription results in more errors than DNA replication?

DNA polymerase synthesizes a new strand. Immediately after, a proofreading enzyme attaches and "checks" the new strand for err

DNA polymerase has better proofreading ability than RNA polymerase.

Transcription proceeds much more quickly than replication. This results in more mistakes by RNA polymerase.

Replication is done very slowly, only a couple base pairs per second, in order to prevent mistakes by DNA polymerase.

More than one of the above is correct.
