Explanation:Basically thymine diamers are mismatched pairs (thymine binds with another thymine instead of binding with adenine) and may lead to unwanted results so the mismatching can be repaired by using two methods which are as follows :

1-the PRE enzyme activated by blue light breaks the thymine diamer and some of the surrounding bonds the strand is cut and DNA polymerase then restores the normal base pairing

2-UVR system breaks dimer creating a gap when a gap is created and the molecules appear unpaired it is filled by proof readers hence restoring normal base pairing.

scientific understanding can always be challenged snd even changed, with new ways of observing and with different interpretation

LuckyWell [14K]

Answer:

True

Explanation:

<em>Conclusions made from scientific research or understanding can always be challenged by anyone with new ways of observing and with different interpretations. This is the essence of the repeatability or reproducibility of scientific experiments.</em>

Scientific research must be reproducible and if the earlier conclusions or understanding is found to be somehow inadequate with overwhelming evidence, they are modified or even changed completely in order to accommodate new facts.

Hence, the emergence of new ways of observing different interpretations can lead to new/different conclusions from the same research. If the new conclusions gain enough evidence, it becomes the new theory.
