Which one of the following statements is true regarding transcription-coupled repair? transcription-coupled repair involves all the major nucleotide excision repair proteins, as well as rna polymerase. transcription-coupled repair occurs in response to the stalling of a ribosome. transcription-coupled repair corrects damage in mrna. transcription-coupled repair occurs only during s phase of the cell cycle.

The correct answer is "Transcription-coupled repair involves all the major nucleotide excision repair proteins, as well as RNA polymerase".

Explanation:

Transcription-coupled DNA repair (TCR) is a type of DNA repair that prioritizes  transcribed strands of actively transcribed genes. TCR is a complex pathway that involves all the major nucleotide excision repair proteins, as well as RNA polymerase. RNA polymerase stalled at DNA lesions and recruits a series of nucleotide excision repair proteins to assess the damage.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
