Question

Which of the following facilitates the reversal of damage to our hereditary material before a permanent mutation can occur?

Multiple choice question.
A. Ultraviolet (UV) light
B. Mutagens
C. Oncogenes
D. DNA repair systems
E. RNA polymerase

Answer 1

DNA repair systems facilitate the reversal of damage to our hereditary material before a permanent mutation can occur. Nucleotide excision repair is one example of a repair mechanism that replaces damaged bases.

Step-by-step explanation:

The DNA repair systems facilitate the reversal of damage to our hereditary material before a permanent mutation can occur. These repair mechanisms are responsible for correcting mistakes made during DNA replication and repairing damage caused by mutagens, such as chemicals and radiation. One example of a repair mechanism is nucleotide excision repair, where enzymes recognize and replace damaged bases, preventing permanent mutations.
