Thymine dimers (DNA bulges) are repaired by: Reverse transcriptase DNA base excision repair system Translocase The ribosome Question 20 1 pts Nonsense mutations occur when introduced into the coding-sequence of a gene. What effect does this have on the protein? Transposons can do these, EXCEPT: Interrupt coding sequence in a gene cause mutations increase protein trafficking Alter transeription of downstream genes

Answer 1

Nonsense mutations in the coding sequence of a gene introduce a premature stop codon, resulting in the production of a truncated protein or no protein at all. This can have various effects on the functionality of the protein, depending on its function. It may render the protein non-functional, disrupt its structure, or affect its stability.
