-Mutations arise from sources other than just mistakes made during DNA replication.
-DNA replication machinery generates errors at a lower rate than RNA transcription machinery.
-Mistakes in transcription are not as critical as mistakes in replication.
-Germ-line mutations can be passed down to offspring.
-Somatic mutations are often passed down to offspring.
-Mistakes in DNA replication do not lead to heritable mutations.
-Mutations in RNA during transcription are not inherited by daughter cells over multiple generations.

Explanation:

The incorrect statements about mutation in the given question are:

-Mistakes in DNA replication do not lead to heritable mutations.

- Somatic mutations are often passed down to offspring.

Mutations are  changes or alteration in the gene sequence of an organisms that may result in significant changes in the organism. mutation is considered as the basis for diversity. Mutations can be silent, lethal or beneficial. Mutations can arise from several sources like mistakes made during replication, translocation of chromosomal segments etc.
