Q: It has been previously shown that disruption of RAD26 in yeast strain W303-1B results in a strain that is deficient in transcription-coupled repair (TCR), the preferential repair of the transcribed strand of an expressed gene over the non-transcribed strand and the rest of the genome. RAD26 encodes a protein that is homologous to Cockayne syndrome group B protein (CSB) and is a member of the SWI2/SNF2 family of DNA-dependent ATPases involved in chromatin remodeling. Like the rad26 mutant, cells from Cockayne syndrome patients are defective in TCR. We examined the role of Rad26 in TCR by disrupting RAD26 in two repair-proficient laboratory strains and, remarkably, observed no effect upon TCR. Our results indicate that disruption of RAD26 alone is insufficient to impair TCR. Thus, W303-1B must already possess a mutation that, together with disruption of RAD26, causes a deficiency in TCR. We suggest that other genes are mutated in Cockayne syndrome cells that contribute to the deficiency in TCR. Surprisingly, deletion of RAD26 results in expression of genes that are repressed by flanking transposon delta elements, an Spt(-) phenotype. The delta elements appear to perturb local chromatin structure. Expression of genes flanked by delta elements in rad26Delta mutants is consistent with a role for Rad26 in chromatin remodeling.

A: Which gene strand is targeted by transcription-coupled repair (TCR)?

Q: When the dog named Judy spotted the first sheep in her life, she did what comes naturally. The four-year-old dog set off racing after the sheep across several fields and, being a city animal, lost both her sheep and her sense of direction. Then she ran along the edge of cliff( ) and fell 100 feet, bouncing off a rock into the sea. Her owner Mike Holden panicked and celled the coastguard of Cornwall, who turned up in seconds . Six volunteers slid down the cliff with the help of a rope but gave up all hope of finding her alive after a 90-minute search. Three days later, a hurricane hit the coast near Cornwall. Mr. Holden returned home from his holiday upset and convinced his pet was dead. He comforted himself with the thought she had died in the most beautiful part of the country. For the next two weeks, the Holdens were heartbroken . Then, one day, the phone rang and Steve Tregear, the coastguard of Cornwall, asked Holder if he would like his dog bark. A birdwatcher, armed with a telescope, found the pet sitting desperately on a rock. While he sounded the alarm, a student from Leeds climbed down the cliff to collect Judy. The dog had initially been knocked unconscious but had survived by drinking water from a fresh scream at the base of the cliff. She may have fed on the body of a sheep which had also fallen over the edge. "The dog was very thin and hungry," Steve Tregear said , "It was a very dog. She survived because of a plentiful supply of fresh water," he added. It was ,as Mr. Holden admitted, "a minor miracle ".

A:
Who spotted Judy after the accident?
