The Conformational Effects of UV Induced Damage on DNA,ecule containing a thymine photodimer. In both models, significant distortions of the nucleic acid helix are observed, including kinking and unwinding at the damage site and numerous changes in the backbone torsion angles relative to their standard conformations.

Negative Control of Viral and Cellular Enhancer Activity by the Products of the Immortalizing E1A G elements and a trans-acting factor(s), possibly the E1A products themselves. The repression of both cellular and viral enhancers with different specificity by the E1A products may be related to common enhancer sequence or factors.

DNA Supercoiling and Gene Expression,ct evidence suggests, however, that DNA supercoiling may also occur and may have strong effects on gene expression. Some possibilities are raised that DNA supercoiling does not necessarily require a gyrase-type activity; in particular, the possibility that the transcription process itself in eukaryotes may cause supercoiling is discussed.
