Which of These Gene Expression Errors Will Result in Heritable

Question

Which of these gene expression errors will result in heritable genetic change?
A)DNA polymerase error introducing an incorrect base
B)RNA polymerase error creating a mutated mRNA
C)RNA polymerase error creating a mutated tRNA
D)RNA polymerase error creating a mutated rRNA
E)All will lead to heritable changes

Accepted Answer

A DNA polymerase error introducing an incorrect base can result in a permanent change in the DNA sequence, which can be passed on to offspring during cell division and replication. The other three errors are related to RNA, which is not directly involved in heritable changes to the genetic code.
