Final answer:
The consequence of errors in DNA replication is mutations that can lead to permanent changes if they are not fixed. Mutations can have serious consequences, such as causing cancer.
Step-by-step explanation:
The consequence of errors in DNA replication is mutations that can lead to permanent changes if they are left unprepared before the next round of DNA synthesis. While most mistakes are corrected by repair mechanisms, if they are not fixed, they can result in mutations. Mutations are defined as permanent changes in the DNA sequence and can have serious consequences, such as causing cancer.
